“Office is a bit disorganized and I had to repeat myself with the doctor a many times but Dr Kellman really knows what he’s talking about and offered in-depth medical testing that other doctors do not seem to offer. His books (that I bought on Amazon) were also extremely helpful and were the first time my disparate symptoms were described and potential diagnosis was possible that would explain my experience to date. My other doctors have been mystified (I have not seen an endocrinologist yet. My thyroid and other labs fall within “normal” range but something is clearly wrong for me specifically).
This doctor does not accept any insurance and payment for the visit and any agreed to testing is due at the time of your appointment(s). My initial intake appointment fee (with no testing) was due at end of appointment. Call ahead for estimate of how much your visit might cost because it can be pricy. I can’t mention specific price due to ZocDoc rules but it was over 500.”

About Dr. Raphael Kellman
Dr. Raphael Kellman is a visionary healer and pioneer in functional medicine. He spearheaded the field of microbiome medicine, revolutionizing medical science. A graduate of Albert Einstein College of Medicine of Yeshiva University with a Doctor of Medicine degree, Dr. Kellman's ability to see deeper causes and connect seemingly unrelated dots has helped many. Though a medical doctor, he primarily uses non-pharmacological treatments, including medicinal herbs and natural compounds grounded in scientific research. He combines a broad vision of healing and keen intuition with deeper-level testing, natural treatment solutions, and cutting-edge technology-based therapies. Together, these offer patients world-class care and solutions to finally enjoy good health.
His approach is rooted in understanding that while the body has many systems, they must work together to maintain balance and wellbeing. Think of the body as an orchestra: although each instrument plays an important role, one out-of-tune trumpet can ruin the entire performance. When one system is ?out of tune,? it can impair the health of the entire body. The microbiome acts as a central command center, influencing and interacting with various systems, organs, and cells. This ecosystem, within our GI tract, is involved in virtually every physiological and metabolic aspect of health. A significant portion of our immune system resides in our gut. Dr. Kellman approaches nearly every condition his patients face with the concept of ?Microbiome First.?
Fee Schedule: If applicable, upon request we can submit claims for potential reimbursement if you have out-of-network benefits. Extensive bloodwork is generally covered by insurance, but specialized testing may require direct payment to a lab or us. Initial consultation: $575; follow-up: $475. We look forward to meeting you!

I thought it was a good experience. I have not received my test results back so haven’t been able to join all the dots yet.

Dr. Kellman looks at your entire body, all systems together interacting. He thinks outside the box and he cares. It was our first visit so no miracles yet but we are very hopeful.

I do not recommend. Doctor was erratic and not a good listener. This provider I not safe for LGBTQ+ people. Take my advice and stay away.

I've struggled with severe stomach issues my entire life. A close friend recommended Dr. Kellman, and I was pleasantly surprised by my experience. The office is centrally located and feels like a high-end spa. Dr. Kellman conducted multiple tests to assess my gut health. He provided a clear diagnosis and prescribed a regimen of probiotics and prebiotics.
Initially skeptical, I was amazed when, after just two weeks, my stomach felt better than it had since childhood. Since then, I’ve been referring all my friends and family to Dr. Kellman. I highly recommend him.

I went to see Dr. Kellman for Hashimoto's, an autoimmune condition that affects the thyroid gland. He helped me cure it and I no longer have it (been free of it for years). I see Dr. Kellman regularly to keep my thyroid levels in check. I also seek his advise for brain health, or any health concern I may have. I can only trust him with my health issues. Dr. Kellman is truly a pioneer in his field, and ahead of his time.

I really recommend doctor Kellman. He really cares for his patients. He made me feel better again after I was very sick. He takes his time for you and listens carefully. He really goes the extra mile to try to help you. Also special shoutout to Genesis, she’s the best! She makes you feel very welcome and is always kind, respectful and helpful.
