"The Eighteenth Judicial District Commission on Judicial Performance agrees, by a vote of 7-1, with one member absent and one vacancy on the Commission, that Judge Colleen Clark MEETS PERFORMANCE STANDARDS." This is an official state commission evaluation of the judge's performance, not an endorsement². The commission's written finding also says: "Some respondents expressed concerns that Judge Clark can be at times slow to make rulings, appears to be visibly frustrated at times, and has opportunity to grow with how she engages with pro se litigants." It also describes her as "fair, calm, punctual, and courteous."²
