I am a board certified and fellowship-trained orthopaedic surgeon who specializes in the repair of fractures in adults. Since 2007, I have been practicing at the University of Rochester where I focus on the repair of complex injuries to bone that occur due to trauma – whether the result of a simple fall or a high energy accident. I am experienced with minimally invasive fracture surgery, repair of complex injuries around joints, and also with fractures that do not heal.

My initial interest in orthopaedic trauma was spurred by the immense rewards of healing traumatic injuries, which are by their nature highly variable. Every injury and every patient present a unique set of challenges, with the goal of treatment being a return to the life and activities that each individual holds dear. I am drawn to the work of helping patients put their trauma in perspective, overcome struggles and return to function.

Research

Medicine is an art of lifelong learning and the research environment at University of Rochester makes this possible. Participation in research reminds us to constantly question our beliefs and keep our perspectives fresh. My early research career focused on the body’s overall response to traumatic injury and evolved to focus on a range of topics related to fracture care. More recently. I have participated in research on fractures that fail to heal, comparison of fracture fixation techniques, and optimal methods for the treatment of hip fractures.

The doctor had my x-rays up on her screen and could discuss the two breaks in my wrist in a very understandable way. I appreciated that she did not talk down to me but rather treated me with respect and as if I was an intelligent person. She has been and is always busy, so the appointment seemed a tad rushed, but overall we got everything done that I hoped for.
