Originally from Pennsylvania, Boston became my second home when I attended Tufts University. After earning my MD at the Tufts School of Medicine, I spent 6 years at the Medical University of South Carolina training in orthopaedic surgery. I returned to Boston for Fellowship training in Hand & Upper Extremity Surgery at the Massachusetts General Hospital. There, I saw a tremendous breadth of conditions affecting adults and children. My particular surgical interests include hand, wrist and elbow arthritis as well as bone and soft tissue trauma in the upper extremity. I have excellent experience and training in both open and arthroscopic treatment methods.  I also have a particular interest in peripheral nerve disorders, including compression syndromes such as carpal and cubital tunnel syndrome, and have a large amount of experience with peripheral nerve repairs and grafting. When indicated, I always try to implement non-operative treatment methods before resorting to surgery.

Outside of work, I enjoy spending time with my family, traveling, swimming, running, and photography.
