what we do

We are continually expanding our services at Marin Weight Loss & Wellness to keep pace with the ever changing environment. Our focal point is weight loss, with both individual and group programs. For our one-on-one consultations, we work with the understanding that every patient is unique, our recommendations are tailored to each patient's lifestyle, dietary needs and goals. Our programs include science-based, medically supervised, health solutions to shedding those extra pounds and keeping them off. We utilize an electronic App to log and track your food and a Body Composition Analysis to determine how your body is changing over time.

During the first month of your program, you will have a consultation with Dr Gail Altschuler, our Medical Director, which includes a physical examination, medical history review and discussion of your goals. Dr Altschuler will continue to supervise your progress during the program. If appropriate, the use of weight loss medications will be considered.

We also offer group classes that focus on weight loss, maintenance, mindful eating and mindfulness meditation. The classes support your goals, connection and community.

Dr Altschuler also heads up our Functional Medicine program, where we take a deeper look into why illness occurs how to restore one’s health by addressing the unique root causes of disease. We also address risks that can precede the manifestation of an illness. We know that although your primary interest may be weight loss, sustained good health is the true goal.

The Functional Medicine approach integrates the latest medical research with a model of care that accounts for each patient’s individual history, unique genetic makeup, and environmental and lifestyle factors.
