I am an orthopedic surgeon at Memorial-Sloan Kettering (MSK) with decades of experience diagnosing and treating sarcomas (malignant tumors) and benign tumors of the bones and soft tissue. I am an expert in surgery to remove tumors while preserving limbs, and I rebuild functional bones and joints with joint replacements and bone transplants. I am proud to be part of a team with a mission to treat people with cancer and to help them continue to have productive lives. In addition to my role as Chief of the Orthopaedic Service at MSK, I am a Professor at Weill Cornell Medical College. I have served as Chair of the Children’s Oncology Group Orthopaedics Section and President of the Association of Bone and Joint Surgeons, among others.
