About Dr. Steven M McMahon
Dr. McMahon has over 30 years of experience in chiropractic care. He is board-certified and has advanced training in physical therapy and nutrition. He uses “gentle” chiropractic treatment to make patients feel better in the shortest amount of time without drugs or surgery.
Dr. McMahon entered the chiropractic field a few years after he sustained a severe back injury, and experienced first-hand the tremendous recuperative benefits of chiropractic care.
Dr. McMahon graduated from Life University’s School of Chiropractic, one of the leading Southern holistic health universities in Georgia. He worked as a staff doctor at a Manhattan chiropractic office for two years before forming his own practice in New Jersey in 1995.
Dr. McMahon moved his practice back to Manhattan in 1998. In 2014, he renovated the office to create a state-of-the-art chiropractic clinic that provides effective chiropractic treatment and a relaxing environment for patients.
During his extensive career, Dr. McMahon has helped people with a variety of ailments and health conditions including headaches, back, leg and neck pain, and scoliosis. He treats patients of all ages—from adolescents to seniors—as well as pregnant women.

My experience was amazing. Dr made sure I was aware of the entire process and visit and also called me after my appointment to ensure there weren’t any other questions I had or needed anything. This place was amazing for me more range of motion and better breathing in just one visit I’m coming regularly as long as is allowed

I actually called 2 friends and told them how wonderful my experience was at Dr Steven McMahon’s office. I was seen on time. Dr McMahon was knowledgeable and had great bedside manner. This is my first visit and to my surprise, he called to check how I feel after treatment. what physician does that? I think I feel better already, cannot wait to have my 2nd treatment this Thursday.
