Dr. John Sellar


Sellar Chiropractic Clinic - 1st Place Winner - 2020 Cappies - Best Chiropractor

We are pleased to announce that Sellar Chiropractic Clinic has been voted 1st Place in the 2020 Cappies People's Preference Awards. Our sincere thanks to all who supported us during these difficult times.

Sellar Chiropractic Clinic will continue to provide award-winning chiropractic care to our patients and new patients are welcome to join the practice.

One of the leading chiropractors in New Hampshire, Dr. John Sellar has been providing affordable chiropractic care to patients in the Concord, NH area for over 25 years. Dr. Sellar was voted Best Chiropractor in the Capital Area in 2017 and 2019. Dr. Sellar was voted "Best of the Best" chiropractors in the Concord, NH area from 2004 through 2019 - 16 years running!

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.
