Justice RICE
delivered the Opinion of the Court.
This original proceeding arises out of the Peoples motion for conflict-free counsel seeking to disqualify the defendants public defenders from continuing to represent him. The People allege that the prior representation of three of their witnesses by attorneys within the Office of the State Public Defender creates a conflict warranting disqualification of the entire Public Defenders Office and the appointment of Alternate Defense Counsel. The defendant and the Office of Alternate Defense Counsel counter that no such conflict exists because neither individual attorney involved in this case participated in the prior representation of witnesses.
We issued a rule to show cause, and we now make that rule absolute, holding that the trial court abused its discretion by disqualifying the entire Office of the State Public Defender from this case.
I. Facts & Procedural History
The defendant, Rodricke Shari, was charged with three counts of first degree murder, three counts of crimes of violence, two counts of first degree burglary, and one count of aggravated robbery after allegations that he caused the death of a woman during the course of a burglary and robbery between May 1, 2008 and May 2, 2008. Shari was represented by two public defenders out of the Golden branch of the Office of the State Public Defender-Rex Hegyi and Daniel G. Katz.
A preliminary hearing was set for October 8, 2008. However, the People filed a motion for conflict-free counsel, alleging that Hegyi and Katz should not be permitted to represent Shari. Defense counsel filed a response, and the October 8 hearing was limited to that issue. ‘
The People alleged that the entire Office of the State Public Defender, including Hegyi and Katz, should be disqualified from representing Shari in this case because of the Offices prior representation of the Peoples three primary witnesses against Shari. The trial court recognized that neither Hegyi nor Katz was individually involved in any of the three witnesses cases.: However, because other attorneys within the Public Defenders Office had represented the witnesses, the trial court disqualified Hegyi and Katz from representing Shari and appointed alternate defense counsel.
The alleged conflict arose out of the Public Defenders Offices prior representation of three witnesses for the People-Lee Jackson, Cheriece Knox, and Brian Levy. Jackson had been Sharis cellmate after Shari was arrested in this case, and Jackson relayed the contents of a conversation he had with Shari to the prosecution. Shari allegedly told Jackson that he was angry with the victim because she was dating other men and had not satisfied a drug debt she owed him. Shari also allegedly stated that he followed the victim home and killed her with a knife and then stole money from her residence.
Knox and Levy told prosecutors that they saw Shari at around 1:30 am. on May 2, 2008, when they were walking along Colfax Avenue in Lakewood. Shari drove up to them and asked Levy to help him obtain some crack cocaine. The two witnesses said Shari had scratches on his face and a large cut on his hand. They got him some cocaine and took him to a hotel to clean up. They had to go to several different hotels because Shari did not want to go anywhere he might be recorded on a video camera. He told them that the police were after him and that he thought he had killed a dude. Knox said Shari had black gloves in his car.
Jackson was represented by the State Public Defenders Office in five previous cases between 2000 and 2002. All five cases were prosecuted in Jefferson County, and attorneys at the Golden office of the Public Defender worked on each case. Some of those attorneys are still with the Golden office, some have relocated to other offices of the Public Defender, and some are no longer working as public defenders.
Knox was represented by the State Public Defenders Office in three cases between 2000 and 2008. No attorney employed in the Golden office was involved in any of those cases.
Levy was represented by the State Public Defenders Office in eight cases between 1995 and 2008. Four of the cases were prosecuted in Arapahoe. County, and four were prosecuted in Denver County. Seven of the eight cases were closed at the time of the trial courts order disqualifying Hegyi and Katz. The eighth case was filed on July 29, 2008 in Denver-two months after Shari was arrested and three months before the hearing on the motion for conflict-free counsel. An attorney from the Denver office of the Public Defender appeared with Levy in the Denver drug court on July 31, 2008. Levy was sentenced to two years of drug court probation. He later failed to appear for a review hearing and was subsequently arrested. No public defender entered any further appearances on Levys behalf after the July 31 probation sentence was entered, and a formal motion to withdraw was filed on October 9, 2008.
The Public Defenders Office enforces an extensive conflict of interest policy. Pursuant to the policy, no information relating to the representation of a client may be transferred between regional offices, though confidential information is sometimes shared among attorneys within the same regional office when necessary to prepare a clients case.
As a result, the policy includes provisions requiring withdrawal where attorneys within the same regional office are currently representing both a defendant and a witness against that defendant. Where a defendant is being represented by an attorney within one regional office, and a witness against that defendant is a current client of another regional office, withdrawal is only required where there is a significant risk that representation will be materially limited.
The policy also notes that a conflict may exist where a witness against a defendant being represented by a public defender was formerly a client of the Public Defenders Office. In these cases, the policy only permits the use of impeachment material that can be gained from sources independent of any confidential communications of the former client. The policy prohibits access to inspect closed file(s) of a client who is now a victim or prosecution witness.
The trial court, finding a conflict of interest imputed to the entire Public Defenders Office, disqualified all attorneys employed by the Office, including Hegyi and Katz, and appointed Alternate Defense Counsel. Alternate Defense Counsel petitioned this court for relief pursuant to C.A.R. 21.
II. Standard of Review
The decision to disqualify counsel generally lies within the broad discretion of the trial court. People v. Harlan, 54 P.3d 871, 877 (Colo.2002). We review a disqualification order for abuse of discretion. Id.; see also § 21-2-103, C.R.S. (2008) (giving trial court discretion to appoint Alternate Defense Counsel where public defender has a conflict of interest).
IIL - Conflict of Interest Rules
An attorney can be disqualified on the basis of a conflict of interest in two distinct ways. First, the attorney may have a direct conflict that prohibits continued representation. Second, the attorney may be associated with another conflicted attorney, and that conflict may be imputed to all associated attorneys. We discuss each in turn, and conclude that no conflict, direct or imputed, existed in this case to disqualify Hegyi and Katz from representing Shari.
A. Direct Conflicts of Interest
The Sixth Amendments guarantee of effective assistance of counsel encompasses a defendants right to conflict-free counsel. People v. Martines, 869 P.2d 519, 524 (Colo.1994) (citing Holloway v. Arkansas, 435 U.S. 475, 483-84, 98 S.Ct. 1173, 55 L.Ed.2d 426 (1978)). A defendants Sixth Amendment rights can therefore be violated by representation that is intrinsically improper due to a conflict of interest Dunlap v. People, 173 P.3d 1054, 1070 (Colo.2007) (quoting People v. Castro, 657 P.2d 932, 943 (Colo.1983)). While judges must be cognizant of potential conflicts when appointing counsel to indigent defendants, the mere possibility of a conflict is insufficient to establish a Sixth Amendment violation. Cuyler v. Sullivan, 446 U.S. 335, 350, 100 S.Ct. 1708, 64 L.Ed.2d 333 (1980).
An attorneys duties to current and former clients are governed by the Colorado Rules of Professional Conduct. Rule 1.7 outlines the duties owed by an attorney to current clients. In order for a Rule 1.7 conflict to exist, the same attorney must represent two clients with adverse interests, or the attorneys representation of one client must create a significant risk of materially limiting the representation of the other client. Colo. RPC 1.7.
Similarly, Rule 1.9 explains a lawyers duties to former clients. A lawyer who has represented a client may not later represent another client in a substantially related matter where the new clients interests are materially adverse to the former clients interests without getting informed consent from the former client. Colo. RPC 1.9. In addition, without getting the former clients informed consent, a lawyer associated with a firm that formerly represented a client may not later represent a new client with interests materially adverse to the former client if the lawyer acquired material, confidential information from the former client. Id.
In the event that a public defender appointed to represent a client is unable to continue representation due to a conflict of interest, alternate defense counsel is to be appointed. § 21-2-101, C.R.S. (2008). For purposes of the Alternate Defense Counsel statute, a conflict of interest includes circumstances in which the state public defender represents a codefendant or a person who is a witness in the case .... § 21-2-103(1)(c), C.R.S. (2008). Consistent with the statute, this court has recognized that a conflict may arise when a defense attorney has previously represented (or is currently representing) one of the prosecutions witnesses. Dunlap, 173 P.3d at 1070. The conflict arises as a result of the duty of confidentiality owed by the attorney to the former client. Id. The existence of this duty may hinder the attorneys ability to cross-examine the former-client-turned-witness testifying against the current client, violating the attorneys duty to zealously represent the current client. Id. In addition, [tlhere is little doubt that public confidence in the legal profession would be undermined if lawyers were free to take part in both the prosecution and defense of a criminal case. Osborn v. Dist. Ct., 619 P.2d 41, 45 (Colo.1980). For these reasons, we often find a conflict where an individual defense attorney has previously represented or is currently representing a prosecution witmess or other party involved in the case against the defendant. See, e.g., People ex rel. Peters v. District Court, 951 P.2d 926, 928 (Colo.1998) (disqualifying two defense attorneys because one of them was currently representing a prosecution witness and had previously represented a person the defense identified as an alternate suspect); Rodriguez v. Dist. Ct., 719 P.2d 699, 704 (Colo.1986) (finding waivable conflict where public defender previously represented prosecutions witness); Castro, 657 P.2d at 932 (disqualifying public defender who was simultaneously representing defendant and district attorney prosecuting defendant); Allen v. Dist. Ct., 184 Colo. 202, 206, 519 P.2d 351, 353 (1974) (reversing trial courts denial of public defenders motion to withdraw where public defender was simultaneously representing prosecutions witness).
-It is clear, then, that in order for a direct conflict to exist, the same individual attorney must be involved in both cases simultaneously, or the allegedly conflicted attorney must have received confidential, material information from the former client. That is not the case here. The only potential Rule 1.7 conflict would be with regard to the representation of Levy, who arguably had an open case being handled by the Office of the State Public Defender while Sharis case was proceeding. However, the Denver public defender who handled the Levy case-and made no appearance on Levys behalf after July 31, 2008-is in no way involved in the Shari case, and neither Katz nor Hegyi had any involvement in Levys case.
There are also potential Rule 1.9 conflicts involving representation of all three prosecution witnesses; Jackson, Levy, and Knox can all be considered former clients of the Office of the State Public Defender. But, as is the case with the potential Rule 1.7 conflict, none of the individual public defenders involved in representing these former clients is involved in the Shari case, and neither Katz nor Hegyi participated in any of the prior cases. As the trial court pointed out, there is no reason to think that either Katz or Hegyi obtained any confidential, material information. As a result, no direct conflict existed warranting disqualification of Katz and Hegyi from representing Shari.
B. Imputed Conflicts of Interest
Because neither Hegyi nor Katz had a direct conflict in this case, they will be disqualified from representing Shari only if the direct conflicts that may exist among other attorneys could somehow be imputed to them. Conflicts particular to individual lawyers within a firm can, in certain ciream-stances, be imputed to the entire firm. Colo. RPC 1.10. However, Rule 1.10 specifically states that [the disqualification of lawyers associated in a firm with former or current government lawyers is governed by Rule 1.11. Id. Rule 1.11, in turn, subjects government lawyers to Rules 1.7 and 1.9. The comments to Rule 1.11 make clear that a government attorneys individual conflicts are not imputed to the entire government agency for which he works. In accordance with Rule 1.11, we have recognized that a distinction must be drawn between an attorney in private practice with a traditional law firm and an attorney associated with a large public or governmental agency. - Osborn, 619 P.2d at 46 n. 8.
As discussed above, the individual public defenders who previously represented the Shari prosecutions three witnesses could potentially be conflicted out of participating in Sharis defense. However, because neither Katz nor Hegyi was involved in those prior representations, and because the conflicts involving those other individual public defenders cannot be imputed to Katz and Hegyi pursuant to Rule 1.11, no conflict exists that warrants disqualifying Hegyi and Katz from representing Shari.
We also note that any concerns regarding the communication of confidential information from the public defenders who previously represented the prosecutions witnesses to Hegyi and Katz are assuaged by the sereen-ing policy, noted above, in effect throughout the Public Defenders Office. The trial court recognized the policys existence and assume[ed] ... [its]) suceess, but then questioned whether Hegyi and Katz would nevertheless feel free to consult the courthouse files in the three prosecution witnesses sixteen cases looking for material or leads to material that can be used to discredit them. In so stating, the court acknowledged the Public Defenders Offices adherence to the rule that government attorneys should generally be sereened to avoid conflicts. However, the court then essentially assumed that Hegyi and Katz would violate the screening policy and imputed any potential conflicts to them, ignoring Rule 1.11s command that conflicts are not automatically imputed among associated government attorneys. Colo. RPC 1.11, cmt. 2.
Through its reliance on precedent referring to the now obsolete Code of Professional Conduct, its failure to appropriately apply Rule 1.11, and its disregard for the Public Defenders Offices extensive sereening poli-ey, we conclude that the trial court abused its discretion in disqualifying the entire Public Defenders Office, including Katz and Hegyi.
IV. Waiver of Right to Conflict-free Counsel
Even if a conflict did exist with regard to Hegyis and Katzs representation of Shari in this case, Shari waived the conflict We have established a four-part balancing test for the waiver of the right to conflict-free counsel, weighing (1) the defendants preference for particular counsel; (2) the [prosecution] witness [sic] right to confidentiality of communications; (8) the publics interest in maintaining the integrity of the judicial process; and (4) the nature of the particular conflict of interest involved. Dunlap, 173 P.3d at 1070 (alteration in original).
A. Defendants Counsel of Preference
A defendants choice of counsel is a decision that should be respected where possible. In re Estate of Myers, 130 P.3d 1023, 1025 (Colo.2006) ([Wle have emphasized the ... importance, in both the erimi-nal and civil contexts, of continued representation of parties by counsel of their choice.). While a defendants Sixth Amendment right to counsel does not guarantee the right to select his appointed counsel, once counsel is appointed, the attorney-client relationship is no less inviolable than if the counsel had been retained by the defendant. Harlan, 54 P.3d at 878 (internal quotation marks omitted). As a result, there is a presumption in favor of a defendants choice of counsel, and [a] defendants desire for continued representation by a court-appointed public defender is entitled to great weight. Id. (quoting Rodriguez, 719 P.2d at 707). To that end, disqualification is a severe remedy that should be avoided whenever possible." Estate of Myers, 130 P.3d at 1025.
As discussed above, a defendants Sixth Amendment right to effective assistance of counsel includes the right to conflict-free counsel. Martines, 869 P.2d at 524 (citing Holloway, 435 U.S. at 483-84, 98 S.Ct. 1173). However, [it is well established ... that a defendant can waive the right to conflict-free counsel so long as the waiver is voluntary, knowing, and intelligent. Dunlap, 173 P.3d at 1070. In order to effectively waive his right to conflict-free counsel, a defendant must be fully advised of existing or potential, conflicts. Martinez, 869 P.2d at 525.
The trial court engaged in the following colloquy with Shari regarding the possibility of a conflict of interest in his case:
THE COURT: [AlJssuming that the People present these witnesses against you in this case, and its pretty obvious to me that they will because they consider these people to be critical witnesses, assuming that they do, I as Judge presume that your lawyers whomever they are whether its Mr. Katz, Mr. Hegyi or someone else as part of representing you zealously, would do whatever they can to attack the credibility of these witness [sic] testimony.... That means, they have an obligation to dig up whatever they can on these people and to use it in whatever way they can to try to discredit them in front of the jury. It would be digging up information and discrediting these people, whom the Public Defenders [O]ffice, apparently even including some of the other Public Defenders here in Golden, have represented in the past. Do you feel comfortable in those cireumstances having these people represent you?
THE DEFENDANT: Yes.
THE COURT: The alternative is that the Court can and would appoint another counsel, someone, one or more lawyers, who have previous experience and ability in murder cases to represent you. Someone who has no prior contact with these three witnesses and that would be at state expense, no charge. Now, what is your thought about this?
THE DEFENDANT: Im fine with these two.
Shari, upon being informed of the potential for conflict and the availability of alternate defense counsel, told the court that he preferred to continue to be represented by his current public defenders, Katz and Hegyi. This preference is entitled to great deference. See Harlan, 54 P.3d at 878. The court made sure that Shari was advised of potential conflicts, and Shari chose to retain his current counsel, waiving his right to conflict-free counsel. This factor, therefore, weighs against disqualification of Katz and Hegyi.
B. Witnesss Right to Confidentiality
The second factor to be considered is the former-client-turned-witnessgs right to confidentiality in communications with his attorney. This factor is weighed less heavily than the others. See People v. Frisco, 119 P.3d 1093, 1095 (Colo.2005) ([Where the courts concern is protecting the interests of former clients rather than protecting the defendant, avoiding mistrial or reversal from later-materializing actual conflicts, or undermining public confidence in the impartiality and fairness of the process, a defendants choice of counsel will not lightly be denied.). Nonetheless, whenever an attorney-client relationship is formed, we presume that the client reposed confidences in the attorney. Osborn, 619 P.2d at 47. Once the attorney-client relationship has ended, the attorney then has a duty not to use that confidential information in a manner that would be detrimental to the client. Colo. RPC 1.9. As discussed above, this creates a potential conflict when an attorney is foreed to cross-examine a former client who is testifying against a current client. See Dunlap, 173 P.3d at 1070.
Importantly, none of the witnesses at issue in this case indicated a problem with Katzs and Hegyis continued representation of Shari. See Rodrigues, 719 P.2d at 707 ([It is of some significance that [the former-client-turned-witness] ... did not join the prosecutions motion to disqualify, nor has she indicated any objection to the public defenders continued representation of the [defendant]."). In addition, this is not a case where the individual attorney representing the defendant previously represented the prosecutions witness. Cf. Dunlap, 173 P.3d at 1070 (finding waivable conflict where defendants public defender previously represented prosecutions witness). As a result, this factor also weighs against disqualification of Katz and Hegyi.
C. - Integrity of the Judicial Process
A court evaluating a motion to disqualify a defendants counsel of choice must also consider the paramount necessity of preserving public confidence in the integrity of the administration of justice. Rodrigues, 719 P.2d at 706. It is important that trials be conducted in an evenhanded manner; that the participants in the adversary process, including witnesses, be protected from unfair tactics; and that the courts maintain the integrity of the judicial system and the highest ethical standards of the legal profession. Id. at 707-08. While disqualification motions are not to be granted lightly, disqualification may be appropriate [when a defendants desire to retain a particular attorney would significantly undermine public confidence in the impartiality and fairness of the judicial process. Id. at 706.
The trial court relied heavily on this factor in granting the motion to disqualify, finding that allowing the Public Defenders Office to continue to represent Shari has a ring of unfairness to the former clients. However, we have often found either no conflict or a waivable. conflict in cases where the same individual attorney currently representing the defendant previously represented a prosecution witness. See, e.g., Frisco, 119 P.3d at 1098 (holding that trial court abused its discretion in disqualifying defense counsel who had himself previously represented prosecutions witness); Rodrigues, 719 P.2d at 708 (finding waivable conflict where defense counsel himself previously represented prosecutions witness). We are not persuaded by the Peoples argument that the possible transfer of some confidential information relating to the prior representation of the witnesses in this case necessarily results in the public impression of unfairness within the judicial process. The sereening policy itself prohibits the sharing of confidential client information between regional offices, so there is no chanee that any information relating to the representation of Knox or Levy could have been transferred to the Golden office. While Jackson was previously represented by attorneys in the Golden office, the policy strictly prohibits access to closed files of a former client who is now a witness against a current client.
Because the sereening policy in effect throughout the Public Defenders Office would prevent any confidential inforrrfation relating to the prior representation of the Peoples witnesses against Shari, concerns about the integrity of the judicial process are unfounded. Therefore, this factor also weighs against the disqualification of Katz and Hegyi.
D. Nature of the Conflict
The final factor to consider in evaluating a motion for disqualification is the nature of the conflict itself. To that end, we have distinguished between actual and potential conflicts, holding that an actual conflict requires an express waiver from the defendant, whereas a potential conflict may or may not require a formal waiver. See Harlan, 54 P.3d at 880. Potential conflicts include a variety of possible scenarios, ranging from a remote possibility that the conflict may arise to a high probability that the conflict will arise. Id.
The trial court here acknowledged that it based its decision on potential conflicts that . create a risk ... that [Sharis] counsel will be materially limited in their ability to represent him. The court went on to list a variety of possible seenarios in which Sharis counsel might obtain some confidential information relating to other public defenders prior representation of the prosecutions witnesses against Shari. Even if it could somehow be said that there was a high probability that any of these conflicts would arise and require an express waiver of the right to conflict-free counsel-and that argument is tenuous at best-Shari clearly exercised a valid waiver of that right, as discussed above. As a result, this factor, along with the other three, weighs against disqualification of He-gyi and Katz.
V. Conclusion
We hold that no direct conflict warranting disqualification of Katz and Hegyi existed, and any direct conflict that may have existed relating to an individual public defenders prior representation of the prosecutions witnesses against Shari could not be imputed to Katz and Hegyi under Rule 1.11. In addition, even if some conflict could be imputed to them, Shari voluntarily, knowingly, and intelligently waived his right to conflict-free counsel. We conclude the trial court abused its discretion in disqualifying Katz and He-gyi. We therefore make the rule absolute and remand for proceedings consistent with this opinion.

. Any potential concern about the transfer of confidential information is lessened by the Public Defenders Offices extensive screening system.
. All the parties have proceeded on the assumption that public defenders are government attorneys under Rule 1.11, and we do so as well.
. The comments to Rule 1.11 state in relevant part: "
Rule 1.10 is not applicable to the conflicts of interest addressed by this Rule. Rather, paragraph (b) sets forth a special imputation rule for former government lawyers that provides for screening and notice. Because of the spe.cial problems raised by imputation with a government agency, paragraph (d) does not impute the conflicts of a lawyer currently serving as an officer or employee of the government to other associated government officers or employees, although ordinarily it will be prudent to screen such lawyers.
Colo. RPC 1.11, ext. 2 (emphasis added).
. The trial court found that the rule of imputed disqualification has been applied to public defenders in some circumstances. - The court cited to McCall v. District Court, 783 P.2d 1223, 1227 (Colo.1989) to support this proposition. While we did say in McCall that [tlhe rule of imputed disqualification applies to both private law firms and public law firms, such as a district attorneys office, 783 P.2d at 1227, that case was applying the Code of Professional Conduct, which has been superseded by the Colorado Rules of Professional Conduct. People v. Witty, 36 P.3d 69, 72 (Colo.App.2000). - Both the Rules and our subsequent cases make clear that conflicts are no longer automatically imputed among government attorneys. See Colo. RPC 1.11, cmt. 2; Osborn v. Dist. Ct., 619 P.2d 41, 46 n. 8 (Colo.1980). We have recently re-affirmed this principle with respect to district attorneys. People v. Perez, 201 P.3d 1220, 1231 (Colo.2009)(Even assuming [the attorneys] prior representation of Perez created a conflict, it would not automatically be imputed to the entire DAs Office under Rule 1.11....}.
