About this clinic

Raphael Kellman, a functional medicine clinic in New York, specializes in integrative assessment and treatment of chronic illness, with particular attention to microbiome-related dysfunction. The practice offers IV therapy, peptide therapy, and ozone therapy as primary regenerative modalities, alongside laser therapy and red-light therapy for supportive care. Treatment plans are individualized following comprehensive functional-medicine workup, and the clinic emphasizes identifying root causes of unexplained symptoms rather than managing isolated presentations. Patients receive ongoing monitoring as protocols are adjusted, and care coordinates with each patient's existing medical team where appropriate.

my wife had a very disappointing experience with this functional medicine practice, especially given the significant financial investment required. What concerned us the most was that during her visit, Dr Kellman appeared to rely heavily on ChatGPT in real time, which felt inappropriate and unprofessional for a specialty medical practice charging premium fees. Additionally, she was told vague information about her lab findings which upon review with another medical proffessional seemed to be innacurate. Overall, the care did not match the cost, expertise, or level of personalized attention that was promised. I would urge prospective patients to ask very detailed questions before committing financially

I have been a patient of Dr Kellman. For 3 years. My experience has been life changing. Dr Kellman pays attention to details. Listens to me explain about my symptoms and puts a plan together. I have total confidence in the Dr. and the office staff is very professional .

He's a genuinely good guy. Trys to help his paitents. He's helped me tremendously with my thyroid issues. He figured it out when traditional doctors told me my thyroid was normal. Turns out it wasn't. Thank you Dr Kellman.
