Dr. Lieberman is my hero! He has operated on both my knees and repaired my torn rotator cuff. I never even needed PT after any of the surgeries performed by him. He is a caring, committed wonderful, sincere and a gifted doctor. I am so blessed to have found him! I have had crappy knees since I was 11 and I am 55 now and he is the only one I trust to KEEP ME MOVING!!!!!
