Dr. Sellar became a chiropractor as a result of and injury suffered as a teenager. He received relief from the constant pain through chiropractic adjustments and decided to become a chiropractor himself to help others benefit from corrective chiropractic care. As Dr. Sellar says, "Chiropractic gave me back my life!"

Dr. Sellar received his Bachelor of Science degree from Excelsior College and his Doctor of Chiropractic degree from Sherman College of Chiropractic. Dr. Sellar is also a member of the Sherman College of Chiropractic Board of Regents. He was recognized by New Hampshire Magazine as one of the "Top Chiropractors for 2015."

In addition to conventional chiropractic adjustment techniques, Dr. Sellar is the only chiropractor in the Concord, NH area, and one of the few chiropractors in New Hampshire, to offer the Sigma adjuster, a computer-aided approach to chiropractic adjustments.

We help people feel better, by resetting the spine and nerves of the body using a computerized medical device that eliminates the guesswork of traditional chiropractic. The Sigma adjuster resets skeletal joints and nerves with absolute precision. It’s painless. It’s immediate. And we eliminate the old-fashioned, “cracking” of manual chiropractic methods.
