DABCN (board qual)


Dr. Merrick is a grad of SUNY at Buffalo, NY and NYU with an associate in Physical Education, a BS in Physical Therapy and a Masters in Physical Therapy& Advanced Kinesiology respectively. Prior to entering the chiropractic field, he was the director of Physical Therapy and Rehabilitation at what is now the Meadowlands Medical Center in Secaucus, NJ. And before that, he worked as a staff PT at the Rusk Institute of Rehabilitation in Manhattan, affiliated with NYU Medical Center. He also worked at the Olympic Sports Medical Training Center in Englewood, NJ as a sports physical therapist, under the direction of Dr. Irving Dardik, founder of the of the Sports Medical Council of the USO in that era. Oddly, Dardik was the force behind getting chiropractic into the Olympics (George Goodhart). He also studied manipulation under the presentations of Stanley Paris and Dr. John Mennell.

After a serious neck injury in competitive sport he reluctantly opted for chiropractic as opposed to surgery and then “saw the light”. Dr. Merrick attended the National College of Chiropractic (now the National University of Health Sciences) where, on fellowship, he developed and taught the first Therapeutic Exercise & Rehabilitation course in a chiropractic institution. It is here that he started his Meridian therapy/Acupuncture and later dry needling practice and has been working at it since.

Dr. Merrick has been teaching post graduate programs in physical therapy, rehab and now dry needling on PG faculty for NUHS, and the NYCC-CCSP program instructing the PT & Rehab section. Merrick also has programs on Evidence Based PT Modalities and “Gait Matters”. He has qualified for his DACBN under the direction and tutelage of the Carrick Institute.

Prior to starting his extended journey as a professional student, Merrick served in Viet Nam as a radio operator. He WAS an avid rugby player and judoka for many years which actually was what got him into chiropractic [the hard way].

He recently retired from the helm at The Merrick Spine Center, a multidisciplinary practice (Chiropractic, PT, acupuncture & wellness) in Manchester, New Hampshire after 32 years. He is also recently retired as a board member (secretary treasurer) for the NH Board of Chiropractic Examiners.

ON-Point Dry Needling program provides 20 CEU’s from NUHS. The program is open to all practitioners (DC, PT, MHT, MD, NPc, Pac, OT,)

I had a persistent discomfort in my left upper abdominal area for several months and so my primary care sent me to a specialist who ran the gamete on me with testing,; MRI, endoscopy Ultrasound and at the end of the day it was a hands up we don’t know. I was seeing Dr. Merrick for acupuncture and was telling him about it and after a little probing he suggested dry needling. I can’t wait to go back to my primary care doc and the specialist. Pain is gone.
