Where medical expertise meets biblical hope in the journey to freedom.

Dr. Don Middleton received board certification in Family Medicine. He has devoted his entire career to serving Arizona families. After 20+ years in family practice and the past decade in addiction medicine, Don has become known for blending medical expertise, compassion, and a whole-person approach to healing.

Don is deeply rooted in his Christian faith and active at Christ Church of the Valley, where he regularly serves on medical mission teams to Kenya and Mexico.
