In pain? Dr Marks is a MUST!

Dr Marks is absolutely one of the best chiropractors in New York. I went from not being able to sit down for more than 20 minutes, to a completely pain free lifestyle requiring only a visit or two every month or so. It took awhile, but through Dr Mark's analysis of x-rays, blood work, supplements, my work out / stretching routine, and overall health his solutions worked perfectly! Definitely much more holistic than you'd ever expect.

Only the best!

Dr. Marks is my go to doctor for everything. Not only does he listen, adjust and inform he will also give me guidance on how best to move forward with any issue I bring to him.

I am completely confident in his capacity to work with on physical conditions and help with emotional ones.

I completely trust his advice and he's always been there for me.

We are all lucky for Dr. Marks.

Dr Marks is a brilliant, caring medical professional.

Always willing to listen, Dr Marks is keen to create a program for your over-all health. He will not only perform chiropractic adjustments, he will go over blood tests and any other test results from other doctors so that he can treat the whole patient.

Longtime patient

I have been a patient of Dr. Marks for fifteen years and he has seen me through countless health concerns. He is a one of a kind doctor who uses very unique and effective methods to treat and diagnose a host of health problems. He has a wonderful way of communicating and treating his patients. I would highly recommend him to anyone who is interested in learning ways to deal with their health in ways that are empowering and educational. He has also helped my other family member. Thanks Dr. Marks

Dr. Marks is simply amazing. I have been coming to him for years!

Dr. Marks is a great chiropractor and nutrition expert. He goes the extra mile and takes the time to diagnose you and offer you different none prescription based options. My back and overall wellness have improved while seeing him.
I would highly recommend him to anyone, and many times I trust his opinion over the one of my primary doctor.

Dr. Marks is a very dedicated practitoner and a great guy.

I have been working with Dr. Marks for a long time, as my issues are very unique and long standing. I always tell him that I don't like when he sends me out for a referral because they cannot compare to his demeanor. He has contacted me on his days off and when he was on vacation. He is as committed to helping me as much as I am. I have been to many practitioners of all types and he is the one that I most prefer. No one can help everyone but he does his absolute best to get you well.

life changing

I saw an ad for Dr. Marks on the subway 15 years ago. It changed my life. I was in need of chiropractic care. Dr. Marks diagnosed and treated my discomfort, including headaches and lack of energy with immediate signs of improvement. His talented approach to my needs has changed my life . I cannot imagine life without chiropractic care for myself and my future family. Bravo, Dr. Marks !!

The Best of the Best

Dr. Marks is not only caring and really wants to know you as a person but he takes the time to understand how and why something is off. Every visit is comforting and I learn something new about how to take care of myself in order to prevent further injury. Definitely recommend him to anyone, especially athletes and anyone looking to learn more about the chiropractic practice along with wellness for a long healthy life.

Best decision ever

I struggled with back pain since an incident over a decade ago. As it worsened, I could barely fly on a plane, and started taking OTC pain medications (which provided temporary relief only). Today, I only need monthly check up - the pain has entirely subsided. Dr Marks offers a holistic approach, including analysis of blood work, suggested supplements, x-rays, exercise routine, and lifestyle. He and Gisell are always very accommodating and flexible with scheduling. Highly recommend!!!
