About Us

The doctors at Walnut Creek Naturopathic are trained in the art and science of natural health care at accredited medical colleges, and licensed by the state Bureau of Naturopathic Medicine. We recognize that the individual — body, mind, spirit — knows its own healing pathways, and we develop therapeutic programs for the individual that are designed to collaborate with natural healing.

Medical Staff

We are family doctors, trained to see patients of all ages and all conditions, and each of us is also trained and experienced in specialties such as integrative cancer care. We work with you to diagnose the underlying causes of disease, and restore optimal health. We emphasize education, prevention, and holistic treatment.

If your condition requires an outside specialist we will refer you to one, and provide supportive care of the whole person while you are being treated by conventional targeted therapies
