Meet Our Team at Healthful Life MD

Dr. Abby Bleistein
Owner, Healthful Life MD

Meet Dr. Abby Bleistein

I am a physician, board-certified in Internal Medicine, Pediatrics, and Obesity Medicine. I am a Colorado native and a graduate of the University of Colorado Health Sciences Center. I practiced primary care for 14 years, treating patients of all ages to improve their health. Frustrated with the standard model of care that left patients shortchanged on time and empathy, I started Healthful Life MD to provide comprehensive, compassionate and coordinated care along with my team of health professionals focused on nutrition, movement, psychology and meal planning and preparation.
