Philosophy of Care

I believe in providing personalized and compassionate surgical care. I like to offer cutting edge surgical treatments that are based on experience and classical principles. I believe complex surgical decisions require careful explanations and shared decision making.

Clinical Interests

Dr. Lee is a fellowship trained fracture specialist who has interest in complex fracture problems. He has a special interest in salvage of failed fracture surgeries, bones that don’t heal correctly, and managing bone loss associated with fractures. He has a special interest in limb lengthening and deformity correction.

Research/Academic Interests

Dr. Lee’s research interests focus on finding new ways to get bones to heal or to create new bone when it is missing. He has a special interest in using autogenous stem cells (from your body) to assist in bone healing and growth.
