Dr. Mahl was great. I came to see him with bad knees and he spoke to me in detail about my problems and I was relieved that I could try something that may benefit me so I would not have to go through major surgical procedures on my knees. After two sessions of prolotherapy on each knee to tighten my ligaments and tendons and strengthen them, I had platelet rich plasma injections performed to each knee, combined with stem cells that Dr. Mahl removed from my iliac bone and from my tummy fat. Dr. Mahl and his staff made me feel very comfortable throughout the day of the procedures, gave me explicit instructions for care at home, and now, some 3 months later, I’m almost completely pain free and my knees feel much stronger. I have recommended Dr. Mahl to my friends and family and tell everyone to look into prolotherapy and stem cells for their joint problems.
