Holcomb Johnston

Dr. Johnston earned her doctorate degree from National College of Natural Medicine (NCNM) and is licensed as a Naturopathic Physician in Montana. She graduated Magna Cum Laude from Middlebury College with a B.A. in environmental policy; attended the University of Montana for her pre-medical education; and studied botanical medicine at the California School of Herbal Studies. She is the owner of and doctor at Sweetgrass Natural Medicine in Bozeman, Montana.

A deep reverence for the Earth, intrigue with medicinal plants, and passion for yoga all led her to the field of alternative healthcare. For four years she received extensive training as a primary care physician with emphasis in treatments for chronic illness, gastrointestinal health, cancer-care, and women’s medicine. In addition to her studies at NCNM, she also completed extra training in Applied Kinesiology, Homeopathy, Biotherapeutic Drainage, Cranial Sacral Therapy, Body Talk and Reiki.

Her belief that the health of the land and the health of humans are intricately interwoven guides her philosophically and medically--just as soil must be cultivated to grow bountiful produce, we can all plant seeds to create optimum wellness. In her free time, Dr. Johnston is an avid organic farmer, cook, and explorer of the mountains. She also enjoys further study of healing arts, Qi gong, climbing, skiing, biking, and running her dogs. Holcomb is honored be a part of the vibrant community of Bozeman and to call the Rocky Mountains home.
