Patient reviews

I was told by my doctor at IBJ that knee replacement was the only solution for my osteoarthritis (OA), and that stem cell therapy wouldn't work. After choosing Regenexx stem cell treatment with Dr. Tanbar, which was covered by my wife's insurance, the result has been remarkable. Recovery was slow, but six months later, I have achieved nearly 100% recovery and am now a firm believer in the treatment's value.

Really great experience with Dr Tambar today. He asked many questions, got a full history, offered confidence and clarity, and was open to all my questions and concerns. One of the best doctor’s experiences I’ve had in recent memory. I really appreciate him and his office!

Dr. Tambar is an exceptional rheumatologist who truly goes above and beyond for his patients. From the moment I stepped into his office, I felt welcomed and cared for. He takes the time to listen attentively, explains everything thoroughly, and ensures that all my questions are answered about my RA diagnosis. His knowledge and expertise are evident, and he genuinely cares about providing the best possible treatment. The office staff is also friendly and efficient, making the entire experience seamless. I highly recommend Dr. Tambar to anyone looking for a compassionate and skilled doctor. Thank you!
