We searched the Colorado Court of Appeals’ weekly announcements from June 1, 2023 to October 22, 2026 and found no decisions on this judge’s rulings. This is not a grade: only appealed rulings appear in those announcements, and a judge with few appealable rulings, or one appointed recently, will often have none.
