Dr. Belton Hallmark, MD – Castle Rock, CO

I have been involved in family practice for the past 32 years, 22 of those years have been here in Castle Rock, Colorado. Currently I own and practice medicine full-time at Douglas Family Medicine. Special aspects of my patient care include providing a wide range of health care services from Family Practice, Internal Medicine, Women's Health, Pediatrics and Geriatrics. As a family physician I value not only the personalized medical care but the relationship built over time with my patients.

At Douglas Family Medicine, I've been honored to receive the Golden Stethoscope Award for my participation in training residents and medical students with the University of Colorado School of Medicine. I have also enjoyed participating in the child health associates program through the University of Colorado School of Medicine in training Physician Assistants.
