I would like to say that TOA is the best. Dr. Robert Greenberg is the best orthopedic doctor. I had two total knee surgeries eight months apart and he changed my life. As a nurse for 32 years I had gotten to the point that I could hardly get around, due to bone on bone knee pain in both knees. Dr Greenberg saved me! Now I’m able to walk and be more active without pain. I can keep up with my grandchildren now. Thank you TOA and Dr. Robert Greenberg! I got my life back.
