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. I learned that I helped people most when I had more time to understand their unique challenges. I started my own practice be able to partner with my patients to formulate individual solutions that work for them, and to surround them with a team to support their long-term goals

I believe the causes of weight gain and obesity are unique and personal to each of us. There are many factors that contribute to every patient’s situation. By working together we can help you understand and conquer the challenges you face to change your life for good.
