About Sara

Sara Sandhya Foster entered the nutritional therapy field in 2011. She received her certification and started her private practice in 2013 through a program developed by Karta Purkh Singh Khalsa, a pioneer in the holistic healthcare field for over 40 years. He is the founder and president of the American Herbalists’ Guild and has authored over 30 books and published over 3,000 articles. He is also an adjunct faculty member at Bastyr University and National College of Naturopathic Medicine.
Under Khalsa’s instruction, Foster learned a tremendous amount of invaluable information about herbal medicine, supplementation and therapeutic diets. Although Foster received her certification 2 years ago she has been studying holistic nutrition independently for more than twenty years, inspired by her father who was also a holistic nutritional counselor.

Foster’s treatment is highly individualized, as she believes each person carries a unique blueprint specific to his or her body. She utilizes a body-positive and choice-centered philosophy that allows each client to direct his or her own healing journey. Through thorough nutritional assessments she develops a customized plan for each client based on the results. Each plan combines foods, nutritional supplements and lifestyle recommendations. Foster’s approach is rooted in compassion as she holds the belief that each person deserves love and acceptance and that growth and change is most effective in a judgment-free atmosphere. Knowing that lasting change doesn’t typically happen overnight, she works with clients at their own pace and level of comfort and ease with making dietary and lifestyle shifts.
