¶ 1. We review the report and recommendation of Referee Hannah C. Dugan that the license of Attorney Thor Templin be suspended for a period of six months for professional misconduct and that he pay the full costs of this proceeding, which are $7,564.50 as of October 19, 2015. The referee also recommends that Attorney Templin be required to make restitution totaling $500 to two clients and that he be required to complete six hours of continuing legal education (CLE), concentrating on civil procedure and/or appellate practice and approved by the Office of Lawyer Regulation (OLR), as a precondition to reinstatement.
¶ 2. Upon careful review of the matter, we adopt the referee's findings of fact and conclusions of law. We agree that a six-month suspension of Attorney Templin's license is an appropriate sanction for his misconduct. We also conclude that the full costs of the proceeding should be assessed against him, and we also agree that he should be required to make resti*353tution totaling $500 to two clients and that he should be required to complete six hours of CLE.
¶ 3. Attorney Templin was admitted to practice law in Wisconsin in 2008 and practices in Milwaukee. His disciplinary history consists of a consensual private reprimand for failing to act diligently and failing to communicate appropriately in a client matter, and for failing to return files. Private Reprimand 2011-04.
f 4. On February 12, 2015, the OLR filed a complaint alleging that Attorney Templin committed 12 counts of misconduct involving four clients.
¶ 5. Attorney Templin filed an answer to the complaint on March 13, 2015. Referee Dugan was appointed on March 31, 2015. On July 2, 2015, the parties sent the referee a stipulation that included a withdrawal of Attorney Templin's answer and his plea of no contest to all counts of misconduct. The parties sent the referee an amended stipulation on July 6, 2015. The amended stipulation provided that the referee could use the factual allegations of the complaint as an adequate basis in the record for a determination of misconduct as to all 12 counts.
¶ 6. The parties jointly recommended that the referee determine that a recommended sanction in the matter be a four-month suspension of Attorney Templin's Wisconsin law license. The parties further stipulated that Attorney Templin should be required to make restitution to two clients in the total amount of $500 and that he be required to complete six hours of CLE concentrating on civil procedure and/or appellate practice, with the coursework to be approved by the OLR, as a precondition to his reinstatement. Attorney Templin represented that he fully understands the misconduct allegations; that he fully understands his right to contest the matter; that he fully *354understands the ramifications of his entry into the stipulation; that he fully understands that he has the right to counsel and has chosen to represent himself; and that his entry into the stipulation is made knowingly and voluntarily and is not the product of plea-bargaining.
f 7. The referee issued her report and recommendation on September 29, 2015. The referee found that the OLR had met its burden of proof with respect to all counts of misconduct alleged in the complaint.
¶ 8. Counts 1-5 of the OLR's complaint arose out of Attorney Templin's representation of J.S. J.S. was divorced from M.S. in July 2008. Attorney Templin commenced his representation of J.S. in December 2008. In August 2011, approximately three years after the divorce judgment, Attorney Templin filed a notice of motion and motion for relief from the judgment of divorce or, in the alternative, to set aside the judgment of divorce for fraud on the court. Attorney Templin's motion challenged M.S.'s financial disclosures.
¶ 9. On October 10, 2011, M.S.'s attorney sent a letter to Attorney Templin, which included a motion for sanctions requesting that Attorney Templin withdraw his frivolous pleadings. The motion was based on legal grounds that included Wis. Stat. § 806.07, requiring a motion for relief from judgment to be filed within one year of the judgment.
¶ 10. On October 25, 2011, Attorney Templin filed an amended notice of motion and motion for relief from the judgment of divorce or to set aside the judgment of divorce for fraud on the court or, in the alternative, to create a trust under Wis. Stat. § 767.125(5). On November 1, 2011, a hearing was held before Calumet County Family Court Commissioner James Fitzgerald. The court commissioner determined *355that Attorney Templin's motion was not timely filed; that at least one of Attorney Templin's arguments involved "great leaps of reasoning that did not make sense;" and that there was no basis in fact for most of the allegations made by J.S. and that such allegations were frivolous. Accordingly, Attorney Templin's amended motion was dismissed with prejudice.
¶ 11. Attorney Templin filed a request for a de novo hearing. A hearing was conducted before Judge Wilber Warren III on March 27, 2012. Judge Warren issued a decision in August 2012 denying the motion to reopen the judgment and also denying the imposition of a constructive trust. Judge Warren found the claims for relief to be frivolous. In a September 10, 2012 order, Judge Warren ordered J.S. and/or Attorney Templin to pay $6,526.22 in attorneys fees to M.S.
¶ 12. J.S. filed a Chapter 7 bankruptcy petition in April 2014, attempting to discharge the "attorneys fees" sanction. Attorney Templin's firm represented J.S. M.S.'s new attorney advised that the attorneys fees obligation was not a dischargeable debt under bankruptcy laws.
¶ 13. M.S. filed a grievance against Attorney Templin with the OLR. Attorney Templin repeatedly failed to respond to the OLR's requests for a response to the grievance. Attorney Templin did finally respond on September 12, 2013.
¶ 14. The OLR's complaint alleged the following counts of misconduct with respect to Attorney Templin's representation of J.S.:
[Count 1] By filing a motion (and amended motion) for relief from a divorce judgment years after the *356applicable time limits had passed and advancing arguments devoid of factual or legal support, Templin violated SCR 20:1.1.1
[Count 2] By knowingly filing a motion (and amended motion) for relief from a divorce judgment years after the applicable time limits had passed and advancing arguments unwarranted under existing law, with no good faith argument existing for an extension, modification, or reversal of existing law, Templin violated SCR 20:3.1(a)(1).2
[Count 3] By filing a motion (and amended motion) for relief from a divorce judgment years after the applicable time limits had passed and advancing arguments devoid of factual or legal support, by later filing a bankruptcy action on behalf of the client seeking to discharge his own sanction obligations imposed by the trial court, and by filing the bankruptcy action one day prior to a scheduling hearing on a Contempt/Show Cause proceeding on the underlying sanction order, Templin took multiple actions on behalf of his client when he knew or when it was obvious that such action would serve merely to harass or maliciously injure another, in violation of SCR 20:3.1(a)(3).3
*357[Count 4] By failing to comply with the September 10, 2012 trial court sanction order requiring Templin and his client (jointly and severally) to pay $6,526.22 to the client's former husband within 30 days of the order, Templin knowingly disobeyed an obligation of a tribunal, in violation of SCR 20:3.4(c).4
[Count 5] By failing to provide relevant information to OLR in a timely fashion, Templin violated SCR 22.03(2),5 which is enforceable under the Rules of Professional Conduct through SCR 20:8.4(h).6
1 15. Counts 6-8 of the OLR's complaint arose out of Attorney Templin's representation of A.H. In 2009, the State of Wisconsin filed a petition to termi*358nate A.H.'s parental rights to his son. Following a dispositional hearing in February 2011, A.H. involuntarily lost his parental rights to his son. Following an appeal and a subsequent trial on remand, the trial court entered an order terminating A.H.'s parental rights to his son. A.H. appealed this order. His appointed appellate counsel filed a no-merit brief on A.H.'s behalf.
¶ 16. On December 5, 2012, the court of appeals entered an order summarily affirming the trial court's order terminating A.H.'s parental rights.
f 17. Pursuant to Wis. Stat. § 809.24(1), a motion for reconsideration of a court of appeals' decision must be filed within 20 days of the court of appeals' order. Pursuant to Wis. Stat. § 808.10(1), a petition for review must be filed with this court within 30 days of the court of appeals' decision. A failure to comply with the 30-day deadline for filing a petition for review deprives this court of subject matter jurisdiction.
f 18. On January 4, 2013, A.H. met with Attorney Templin and paid him $300 in cash to review his case file for purposes of possibly filing a petition for review. A.H. believed he had until January 7, 2013, to file a petition for review. In fact, the filing deadline was January 4, 2013. Attorney Templin failed to advise A.H. that, subsequent to January 4, 2013, nothing further could be done on the case.
¶ 19. A.H. attempted to reach Attorney Templin in January and February of 2013 without success. In March 2013, A.H. submitted documents to Attorney Templin in an attempt to show his continued efforts to see his son. In April 2013, Attorney Templin met with A.H., returned his files, and stated there was nothing further to be done in the matter.
*359f 20. A.H. filed a grievance with the OLR against Attorney Templin. Attorney Templin failed to respond to the OLR's requests for a response to the grievance.
¶ 21. The OLR's complaint alleged the following counts of misconduct with respect to Attorney Temp-lin's representation of A.H.:
[Count 6] By failing to respond promptly to [A.H.'s] multiple requests for information regarding his case, Templin failed to comply with reasonable requests by [A.H.] for information, in violation of SCR 20:1.4(a)(4).7
[Count 7] By failing to explain to [A.H.] that the deadline for filing a Petition for Review with the Supreme Court, or that all other applicable appellate deadlines, had expired on or before January 4, 2013, Templin failed to explain matters to [A.H.] in a way that would permit him to make informed decisions about his representation, in violation of SCR 20:1.4(b).8
[Count 8] By accepting a $300 fee to review [A.H.'s] file for purposes of a potential appeal to the Supreme Court, on the same day as the deadline for filing any kind of appeal or petition for review expired, thereby precluding any meaningful action in the case, Templin charged an unreasonable fee, in violation of SCR 20:1.5(a).9
*360¶ 22. Count 9 of the OLR's complaint arose out of Attorney Templin's representation of V.K., who retained Attorney Templin in May 2013 to commence a divorce action. Attorney Templin prepared legal papers purportedly for the purpose of commencing the divorce action and mailed them to the Racine County Clerk of Court for filing. The clerk of court returned the divorce pleadings, unfiled, to Attorney Templin with a note indicating that the family court commissioner would not accept the documents for filing because Attorney Templin also needed to file an order to show cause and affidavit for temporary relief.
¶ 23. Attorney Templin prepared an order to show cause and affidavit for temporary relief and mailed the documents to the clerk of court. The documents were again returned with a statement that Attorney Templin had failed to properly follow local Racine County court rules. Thereafter, Attorney *361Templin downloaded the court documents that are accessible online for pro se litigants and filled out the information necessary to initiate the divorce action on behalf of V.K. Those documents were submitted to the clerk of court and were once again rejected. V.K. fired Attorney Templin via email on or about July 22, 2013.
¶ 24. The OLR's complaint alleged the following count of misconduct with respect to Attorney Templin's representation of V.K.:
[Count 9] By failing to properly prepare and file [V.K.'s] Petition for Divorce in Racine County Circuit Court, Templin failed to provide competent representation to his client, in violation of SCR 20:1.1.
¶ 25. Counts 10-12 of the OLR's complaint arose out of Attorney Templin's representation of C.B., a veteran who had a history of receiving medical care from the Veterans Administration (VA). In June 2008, C.B. was involved in a serious auto accident which resulted in him being flown to Froedtert Memorial Lutheran Hospital (Froedtert) where he remained for approximately three months. After payment of certain amounts by the VA, the amount owing from C.B. to Froedtert was $79,442.07.
f 26. On August 28, 2012, Froedtert filed a summons and complaint against C.B. in Milwaukee County circuit court. C.B. met with Attorney Templin on September 21, 2012, and discussed the need to file an answer and a third party summons and complaint against the VA.
¶ 27. Attorney Templin filed an answer and affirmative defenses on September 24, 2012. A pretrial conference was held on November 5, 2012. The scheduling order issued that day imposed a December 5, 2012 deadline for filing amendments to the pleadings, *362including the naming of any additional parties. The scheduling order imposed a deadline of March 5, 2013, for the parties to file all dispositive motions, imposed deadlines to identify witnesses and damage claims, and imposed a deadline for discovery, as well as a deadline to complete mediation.
¶ 28. On December 5, 2012, Attorney Templin filed a third party summons and complaint against the VA. Despite apparent efforts to obtain service on the VA, service was never obtained. Attorney Templin never filed a witness list on behalf of C.B.
¶ 29. On March 5, 2013, Froedtert filed a motion for summary judgment with supporting memorandum and affidavit. Attorney Templin did not file any responsive pleadings. On April 22, 2013, Attorney Templin sent an email to Froedtert's counsel indicating he never received the summary judgment motion. Another copy of the motion was sent to Attorney Templin.
¶ 30. On April 22, 2013, Attorney Templin sent a letter asking the judge for an adjournment of the April 24, 2013 summary judgment motion hearing. Attorney Templin's request was denied.
¶ 31. The scheduling order had also required the parties to complete mediation before April 4, 2013. The attorneys never communicated over the subject of mediation.
¶ 32. On April 24, 2013, the circuit court granted Froedtert's motion for summary judgment. Attorney Templin never adequately advised C.B. about the pending summary judgment motion or various legal options available to him concerning the motion. C.B. received no communication or contact from Attorney Templin after April 24, 2013. Ultimately, C.B. filed bankruptcy in 2014 and the judgment in favor of Froedtert was discharged.
*363¶ 33. The OLR's complaint alleged the following counts of misconduct with respect to Attorney Temp-lin's representation of C.B.:
[Count 10] By failing to properly serve the VA; by failing to submit a witness list or detailed damage claims; and/or by failing to respond to the Motion for Summary Judgment filed by the plaintiff in the case, Templin failed to provide competent representation to his client, in violation of SCR 20:1.1.
[Count 11] By failing to secure service on a third-party defendant, file a witness list as required in the Scheduling Order, pursue mediation, or file any dis-positive motions, Templin failed to provide diligent representation to his client, in violation of SCR 20:1.3.10
[Count 12] By failing to advise [C.B.] of the pending Motion for Summary Judgment, or the subsequent entry of a judgment against him, as well as failing to discuss the options available to him regarding his case, Templin failed to explain matters to [C.B.] sufficiently to enable him to make informed decisions regarding his representation, in violation of SCR 20:1.4(b), and failed to keep his client reasonably informed about the status of the matter, in violation of SCR 20:1.4(a)(3).11
¶ 34. By entering into the amended stipulation, Attorney Templin admitted the facts underlying all 12 counts of the OLR's complaint. The referee concluded that the OLR met its burden of proof as to all 12 counts. The referee further agreed with the parties' amended stipulation that Attorney Templin be required to make restitution in the amount of $300 to *364A.H. and $200 to V.K. The referee further agreed with the parties' amended stipulation that Attorney Templin be required to complete six hours of CLE, concentrating on civil procedure and/or appellate practice and approved by the OLR, as a precondition to reinstatement.
¶ 35. Turning to the appropriate sanction, while the parties' amended stipulation jointly recommended a four-month suspension, the referee concluded that a six-month suspension was appropriate. The referee commented that the one mitigating factor in the case was Attorney Templin's lack of an extensive disciplinary history. The referee identified a number of aggravating factors, including multiple offenses, a pattern of misconduct, an intentional failure to comply with rules or orders of the disciplinary agency, and vulnerability of the victims.
¶ 36. The referee noted that Attorney Templin is a staff attorney employed at a nonprofit law firm directing services for economically disadvantaged clients who have few or no lawyer retention options. The referee also found a lack of remorse or acceptance of responsibility for Attorney Templin's actions, as well as a significant number of violations occurring in a relatively short period of time since he was licensed to practice law. The referee also expressed concern about Attorney Templin's understanding of his violation of supreme court rules, the seriousness of the violations, the inappropriateness of his conduct, and the effect of his violations of the rules. The referee noted that, while the disciplinary proceeding was pending, Attorney Templin attempted to voluntarily resign from the State Bar. His resignation request was held in abeyance pending the outcome of this disciplinary proceeding. The referee also commented that she was con*365cerned about Attorney Templin's understanding and attitude towards meeting the professional standards imposed on a member of the bar, and said his " conduct during these proceedings raises substantial concerns about [his] understanding of and attitude toward court proceedings and toward future clients' needs and expectations."
¶ 37. The referee concluded that a six-month suspension was necessary for Attorney Templin to understand and accept the responsibilities of the legal profession and the ethical constraints placed upon its practice. She said the resultant full reinstatement proceeding, pursuant to SCRs 22.29-22.33, is necessary for the court to be certain that Attorney Templin has complied with the supreme court rules during the term of his suspension and that he is prepared to comply with the standards of professional practice and the expectations of clients served under a Wisconsin law license.
¶ 38. A referee's findings of fact are affirmed unless clearly erroneous. Conclusions of law are reviewed de novo. See In re Disciplinary Proceedings Against Eisenberg, 2004 WI 14, ¶ 5, 269 Wis. 2d 43, 675 N.W.2d 747. The court may impose whatever sanction it sees fit, regardless of the referee's recommendation. See In re Disciplinary Proceedings Against Widule, 2003 WI 34, ¶ 44, 261 Wis. 2d 45, 660 N.W.2d 686.
¶ 39. There is no showing that any of the referee's findings of fact are clearly erroneous. Accordingly, we adopt them. We also agree with the referee's conclusions of law that Attorney Templin violated the supreme court rules set forth above.
*366¶ 40. With respect to the appropriate level of discipline, upon careful review of the matter, we agree with the referee's recommendation for a six-month suspension of Attorney Templin's license to practice law in Wisconsin. Although no two disciplinary proceedings are identical, a six-month suspension is generally consistent with the sanction imposed in In re Disciplinary Proceedings Against Hartigan, 2005 WI 3, 277 Wis. 2d 341, 690 N.W.2d 831 (attorney's license suspended for six months for six counts of misconduct involving two client matters) and In re Disciplinary Proceedings Against Boyd, 2009 WI 59, 318 Wis. 2d 281, 767 N.W.2d 226 (attorney's license suspended for six months for 13 counts of misconduct arising out of five client matters).
¶ 41. We agree with the referee's recommendation, based upon the parties' stipulation, that Attorney Templin be required to make restitution to A.H. in the amount of $300 and to V.K. in the amount of $200. We further agree that, as a precondition of license reinstatement, Attorney Templin be required to complete six hours of CLE, concentrating on civil procedure and/or appellate practice, as approved by the OLR. We also find it appropriate to impose the full costs of this disciplinary proceeding on Attorney Templin.
