Thomas Cowan, M.D.

tom photo web2Dr. Tom Cowan discovered the work of the two men who would have the most influence on his career while teaching gardening as a Peace Corps volunteer in Swaziland, South Africa. He read Nutrition and Physical Degeneration by Weston Price, and a fellow volunteer explained the arcane principles of Rudolf Steiner’s™ biodynamic agriculture. These events inspired him to pursue a medical degree. Tom graduated from Michigan State University College of Human Medicine in 1984. After his residency in Family Practice at Johnson City Hospital in Johnson City, New York, he set up an anthroposophical medical practice in Peterborough, New Hampshire. Dr. Cowan relocated to San Francisco in 2003.

Dr. Cowan has served as vice president of the Physicians Association for Anthroposophical Medicine and is a founding board member of the Weston A. Price Foundation™.  During his career he has studied and written about many subjects in medicine. These include nutrition, homeopathy, anthroposophical medicine and herbal medicine. He is the principal author of the book, “The Fourfold Path to Healing”, which was published in 2004 by New Trends Publishing and is the co-author of “The Nourishing Traditions Book of Baby and Child Care,” published in 2013. He writes the “Ask the Doctor” column in Wise Traditions in Food, Farming and the Healing Arts, the Foundation’s quarterly magazine, and has lectured throughout the United States and Canada. He has three grown children and currently practices medicine in San Francisco where he resides with his wife, Lynda Smith Cowan.

Dr. Cowan sees patients at his office in San Francisco, does long-distance consults by telephone, and is accepting new patients. He also gives lectures and presentations.


Sabine Luisi, Therapeutic Diet Consultant, Manager

Sabine’s approach to healing arts and nutrition has been evolving over the last 20 years.  Her interests in holistic medicine began in 1994 with the entrance into a 1000-hour certification in acupressure that included various styles of acupressure, Chinese nutrition, remedies, counseling techniques, and guided imagery.  In 1999, she was introduced to the work of Weston A. Price through Sally Fallon Morell’s presentation, and her book, Nourishing Traditions.

After moving to San Francisco and implementing these diet principles for many years, she began working with Dr. Cowan in 2006, where she has continued to expanded her depth of knowledge in alternative medicine.  Since then, she has been helping Dr. Cowan with the creation, research, and consultation of the various diet protocols, and in 2012, was additionally trained by Dr. Natasha Campbell-McBride as a doctor’s assistant for the GAPS Diet.

Her passion for food, holistic medicine, and alternative care accessibility have stimulated other projects such as the Community Supported Healthcare Plan, developing in-office treatments and services, and organizing resources for patients.


Laura Lion, Receptionist, CNC

Laura is a certified Nutrition Educator and Consultant who completed her studies at Bauman College in Berkeley. She discovered a passion for eating a whole foods diet while searching for natural ways to take control of her health.  Laura has suffered some family losses related to heart disease and cancer; she has witnessed other family member’s lives deteriorate even while working with their doctors to treat their diseases, and in 2006 she was diagnosed as pre-diabetic. After two years of following her doctor’s advise and taking a Statin drug and a cholesterol lowering medication, she decided there had to be a better way and ceased taking the medicines. This was the beginning of many changes in her life that have contributed to her well-being today.

Laura’s passion to help others help themselves and her excitement about the field of healing through nutrition led her to Bauman College to embark on a journey of holistic nutrition and healing. Laura draws from many of the modalities she’s learned at Bauman College, continuing education courses, continual reading and research, and the wealth of information she learns by working with Dr. Cowan.  Laura’s personable nature allows her to reach individuals in a non-threatening manner and coach them through lifestyle changes so they too can take control of their own health.

Laura’s husband, two children and two granddaughters are important factors that keep her motivated to stay healthy. Other factors include her love for hiking, skiing, and camping in the mountains, spending time in the outdoors with friends and family, and preparing wonderful healthy foods.  Her determination, courage, and optimism have allowed her to be free of medication, feel more energetic, and live a much healthier lifestyle. She is well versed in the Nourishing Traditions diet & the Standard Process Purification Program and is available for consults through our office for existing patients.
