Teaching Facility For Surgeons Around The World
Our goal and priority is to provide the highest quality of care and a compassionate healthcare experience. Our history of over 10 years of patient excellence and continuous innovation ensures you can trust us to help you get back to your best. We look forward to caring for you and assisting you back to the best quality of life you can have.
The practice of orthopedic surgery is constantly evolving due to changes in technology, economic and regulatory factors. Our approach to patient care involves keeping up with the latest advances and at the same time not ignoring the art of caring. We believe in a thorough discussion about the diagnosis and treatment options with the patient/family.This helps in making good decisions and helps recovery after surgery. A majority of my practice consists of treatment of arthritis. This includes joint replacement of the hips, knees and shoulders.
