Stephen Tag D.C.

Dr. Stephen Tag graduated from New York Chiropractic College in 1989. He had a chiropractic practice on Nantucket Island from 1990 till 2007, when he moved and opened a practice on Cape Cod. He has been studying Applied Kinesiology with Dr. Leaf and many other great Applied Kinesiology teachers since 1994.

An avid lifelong rock and ice climber, hiker, surfer, cyclist, and skier, Dr. Tag has treated many hard core athletes, as well as lots of weekend warriors and couch potatoes. Inactivity is very stressful and leads to premature aging, and as Sir Isaac Newton said; “A Body In Motion Tends to Stay in Motion; a Body at Rest Tends to Stay at Rest”.

Dr. Tag is honored to have the opportunity to work several days a week in Plymouth with Dr. Leaf, and is looking forward to helping take care of the many patients who come from near and far to experience this unique and incredibly effective approach to solving health problems and maximizing the potential we all have to keep living healthy, happy, and active lives.
