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!

If you have RA - and the body/mind changes that come with it - this is the place you should be. Dr Tambar is calm and a true listener. My visits with him have never felt rushed. He takes time to understand what you are feeling - physically, mentally and emotionally. He is holistic in his approach but combines this with the latest medical treatments. I am now going through a new and painful shoulder episode which my medical doctors have been scrambling unsuccessfully to treat. He has pinpointed and targeted this accurately - but more than that, he has understood where I am in this pain journey. If you need help from a true listener and innovative healer, I would give him a try. 🙏

My husband seen Siddharth Tambar MD today. Our experience was great. He was very thorough, listened to all of our concerns and explained everything. We went thinking we were only doing a consultation and ended up getting treatment at this appointment. Very nice man and didn’t rush through the appointment. My husband felt very comfortable.
