A locally owned dental practice in Peoria since 1976

Copper Sky Dental is a locally and privately owned dental practice, not a corporate chain. Located in Peoria on the border of Sun City, we are proud to serve adults and seniors throughout the West Valley with the kind of personal, attentive care that only an independent practice can provide.

Dr. Robert Holyoak is celebrating 50 years of caring for his neighbors. He has been in this office since 1976, building real relationships with the people he serves. Dr. Lisa Kubik lives in the West Valley too.

When you walk through our door, you are met by a small, familiar team. We take time to listen, explain your options honestly, and create treatment plans that respect your goals, budget, and comfort level.
