Britton Mann, Doctor of Acupuncture and Oriental medicine

Director of Acupuncture Program

I hold a Doctorate in Acupuncture and Oriental Medicine, the highest-level credential available to practitioners of Chinese medicine in the United States. 
I have had a life-long interest in traditional Asian healing modalities and martial arts. Growing up in New York City, I studied Japanese karate for nine years. During these formative years I received healing and teaching from a formidable taiji master named Ron NaVarre.
After four years at Williams College, I attended school for therapeutic bodywork in Boulder, Colorado. I learned shiatsu massage from Dr. Jeffrey Dann, and took up a sincere study of yoga with Richard Freeman.
Subsequent to training in Colorado, for six years I taught yoga and maintained a bodywork practice in Norwich, Vermont. During this time I had the opportunity to study extensively with Rodney Yee and other luminaries in the Iyengar yoga tradition, both in the United States and in India.
Seeking a comprehensive and holistic system of internal medicine, I moved to Portland, Oregon, and earned a master’s degree from the Classical Chinese Medicine program at the National College of Natural Medicine. At NCNM, I had the great fortune to have Drs. Haosheng Zhang and Heiner Fruehauf as herbal medicine instructors, Dr. Edward Neal as a classical literature and medical diagnostics instructor, and Dr. Bob Quinn as a bodywork and acupuncture mentor. I spent three formative years in private practice with Dr. Haosheng Zhang at his acupuncture clinic in southeast Portland.
My interest in clinical research and medical scholarship led me to pursue a doctoral degree at the Oregon College of Oriental Medicine. This program included extensive training in western biomedicine and evidence-based approaches to acupuncture. During this time I conducted a nationwide survey of attitudes towards acupuncture among pain medicine physicians. I am a published author in western and Chinese medicine journals.
I am board certified in acupuncture and herbal medicine, hold licensure in New Hampshire and Vermont, and am a member of the Vermont Acupuncture Association and the New Hampshire Acupuncture and Asian Medicine Association. In addition, I serve on a national professional steering committee and lecture regularly on the subject of Chinese medicine.

Stefan practices a lineage of Chinese medicine that combines – within the context of a single clinic visit - tuina (Chinese medical massage), Craniosacral therapy, acupuncture, and Chinese herbs. Stefan has been studying and practicing this lineage of medicine for over ten years.
He is a graduate of National University of Natural Medicine in Portland, Oregon, where he received his Masters of Science in Oriental Medicine. His time in school was focused on the clinical application of classical herbal formulas from the great Chinese herbal compendium the Shang Han Lun. Patients are often prescribed herbal formulas at the finish of the treatment, to augment and support the clinical efficacy of the manual medicine.
He has been practicing the Chinese internal martial arts for almost twenty years, training in several lineages of baguazhangxingyiquan, and taijiquan. He also trains a variety of qigong forms, some parts of which are often taught to patients as movement therapy. He is an Instructor in the North American Tang Shou Tao Association, teaching qigong, baguazhang, and xingyiquan locally.
With over a decade of experience in Chinese manual medicine, and an ongoing dedication to training the internal martial arts as medicine for both himself and his patients, Stefan brings a well-rounded approach to his medical practice.
