Highly recommend Dr. Greenbaum. He operated on my knee and did stem cell and now I could actually hike without any pain. I also had to have a full rotator cuff repair because I ripped everything in a snowboarding accident. I could not believe how quickly I bounced back and how much flexibility I have in my shoulder while many others told me horror stories about there rotator cuff repair surgery from other surgeons. I am grateful that I met Dr. Greenbaum
