I have been a patient of Dr Kellmans for a little over a year. I was suffering from a laundry list of symptoms including weight gain, brain fog, depressed mood, etc and had seen numerous doctors who all said my tests looked normal. Despite what many doctors said, I knew something was wrong. Dr Kellman took the time to really listen to what I was experiencing and through additional testing, discovered that I had a severely under active thyroid. With his treatment plan, I lost all the weight I had gained and feel better than I ever have. He has a very holistic approach to healing and wants to treat the problem , not just the symptoms. I am so grateful to Dr Kellman and the rest of the staff.


His staff and nurses are super helpful!

I have been seeing Dr. Kellman for a few years. I came in with many symptoms, many related to Hashimotos thyroiditis: fatigue, weight gain, thinning hair, digestive issues. He has been so on target in his ability to diagnose and treat, not only symptoms, but the underlying cause of my symptoms. With his recommendations and treatments, I feel so much better. In addition to that, I have been able to avoid colds and the flu without any vaccines. Besides all that, he is a doctor who truly cares about his patients and who stays on top of all the latest research and treatments. When all other types of medical treatments failed to work for me, the Kellman Center has been an oasis of knowledge and kindness.


I would highly recommend Dr.Kellman.

I saw Dr. Kellman, early this year, for a chronic ailment.  I was unable to eat, various food groups, that was part of my regular diet, prior to 2020.  The restricted diet, led to  me being nutrient deficient, resulting in some other health issues.

Each patient issues are unique, as one should factor in all their health conditions,before starting any treatment.

Dr Kellman, actively listened to my concerns, and asked pertinent questions, to diagnoze and treat. It helps that he has a affable personality and puts a patient at ease to talk.

The positive Sibo test ,confirmed his diagnosis, that my microbiome, got compromised in 2020. To put in context ,I was prescribed a very high dose of Prilosec(80mg!) by a well known city gastroenterolgist for several months in 2020. Other doctors later felt the diagnoses and treatment was incorrect.

Dr. Kellman explanation was, that a thyroid patient (me) ,has anyway low stomach acid, and giving high dose of PPI is counterproductive. It compromised by microbiome, and I never really recovered,from the overdose of PPI.

His treatment plan of several months (antibiotic,herbal microbials and few supplements ) has helped and I am able to eat more food now and my symptoms have eased.

In short, Dr.Kellman’s approach was to holistically,solve a chronic health  problem, that other doctors were unable to do so. I would highly recommend Dr.Kellman.


I highly recommend with practice.

At this location I had a consultation with Sandra McKenzie who is the direct doctor under Dr. Kellman.

This experience was unlike any other doctor appointment I’ve ever been to. During my initial consultation she spent at least an hour with me of constant problem solving conversation. When I walked out of the appointment I had all the supplements and healthy medications in route to my house electronically for discount prices. This was the only doctor out of 10 different doctors over 6 years that was able to find my issue. I highly recommend with practice.

The money is worth not having deal with insurance doctors who do not offer healthy alternative treatments. This practice also offers IVs and multiple different forms of new treatments. I went for stomach issues.


Very happy with the service and treatment I’m receiving at the Kellman center

Very happy with the service and treatment I’m receiving at the Kellman center. I suffered from debilitating brain fog for several years and Dr Kellman and staff cleared it up in roughly 60 days through various IVs, supplements and thyroid meds. It wasn’t cheap – but not because he’s more expensive than other doctors – just because it is paid out of pocket rather than thru insurance. Will continue to see Dr Kellman until I’m 120%.


Office staff is incredibly wonderful and helpful

Dr Kellman helped my mother resolve a severe endocrine condition in a matter of weeks with infusions. She was falling and was getting very scary diagnoses. Dr Kellman immediately understood the magnitude of the problem and diagnosed her correctly. Her severe symptoms are healed. She continues to monitor her thyroid with Dr Kellman and we are looking forward to helping her achieve a total physical transformation in the coming months.

Pros: Takes his time and is incredibly compassionate. Office staff is incredibly wonderful and helpful. Nursing staff is a cut above the rest.

Cons: Because he actually tries to cure you, good luck with your medical plans!


Thank You!!!

After a false start elsewhere, Dr. Kellman exceeded expectations, shared great insight, and created a thorough game plan to help toward recovery and perhaps even optimal health!


Dr. Raphael Kellman is the Best!

Dr. Raphael Kellman is the Best! I saw him back in 2009 when my finger tips disappeared and I had to wear band-aids. I wanted a medical doctor that also believes in alternative medicine. Dr. Kellman takes his time listening to all my complaints, history, and current issues. I started seeing him again last January 2017. I was again very tired, feeling bloated, skin was dull, and simply no energy. I was very stressed out. Now my friends and family think I look younger than ever, my energy is back, but we still have some work to do to getting me balanced again. When you book your appointment, be sure you leave plenty of time, maybe not plan anything afterwards.


I highly recommend Dr Kellman and his staff at the Kellman Center

I highly recommend Dr Kellman and his staff at the Kellman Center, especially if you are struggling with undiagnosed symptoms, auto-immune diseases, gut issues, thyroid problems, Chronic Fatigue or Lyme Disease. Dr Kellman and his entire staff have a vast knowledge and significant experience in treating these conditions. Everyone at the Kellman Center takes an integrative, functional approach to treating patients. This means looking at you as an individual, understanding your personal health history and your current health situation. The goal is to heal the underlying causes of the symptoms you are displaying. Dr Kellman and his staff take time to listen, and to explain lab results, why a specific supplement or medication is necessary, and how a treatment plan will help you heal. This is about healing the body, not just treating the symptoms.

Dr Kellman and his staff at the Kellman Center are incredibly caring and highly knowledgeable. I would go back to Dr Kellman any day if I still lived in NYC, and I continue to recommend Dr Kellman and his staff to anyone in the NY area looking for a holistic, integrative and functional approach to medicine.
