Had a total hip replacement 7/18/19. I am doing very well. I will be 74yrs. old, this year. I was able to go back to work, in 6 weeks. Dr. Lementowski, gave me back my mobility, and I guess you can say; my independence. Before the surgery, the pain was excruciating. Thank you, Dr Lementowski, for your kindness, caring, and professionalism.

Dr Peter Lementowski is very profesional and kind, When I say the doctor and all his staff made me feel that I was in safe hands and even made me smile when I left, then you can believe they are the best. I don’t write to much but with this experience I need to.
