Gail Altschuler, MD, Medical Director

Marin Weight Loss & Wellness was founded on the belief that treating the underlying issues of overweight and obesity can greatly improve an individual’s health, appearance and overall well-being.

Dr. Altschuler has a deep understanding of the challenges her patients face. She learned this from her own experience, having lost 50 pounds herself  and kept it off these past 11 years. With her compassionate and inspirational guidance, she has helped thousands of men and women achieve a healthy weight while helping them to build the skills to maintain it lifelong.

Dr. Gail, as her patients call her, first became interested in weight loss when she realized that she was clinically obese herself, and yet, couldn’t lose weight.  She began her own weight loss journey with the skills learned from the Obesity Medicine Association. With new skills and understanding  she changed her focus from Family Practice to Bariatric Medicine, the only specialty dedicated to addressing the complex and unique issues surrounding obesity and long-term weight loss success. With these skills she was able to address the root cause of illness, rather than just treating the symptoms.

“After 25 years of telling people that they should lose weight, I was shocked at how much better I felt. Of course, the next thing to do was to share my enthusiasm and knowledge with my patients.  So much of the illness, pain, and frustration I saw in my family practice patients was, in fact, lifestyle-related, the result of being overweight or obese. What a privilege it is to guide people as they regain their health, vitality, self confidence and sense of well being.”
