Clinical Interest for Patients

My greatest area of interest is the treatment of adult spine deformity. This includes many problems that cause issues with posture, including scoliosis and kyphosis. I am also interested in treating patients who have had previous surgery and continue to have issues.

Care Philosophy

I treat patients as I would like to be treated myself, or as I would want my family members treated. It is important that patients are informed and active in the decision making process, and I feel this is a critical part of my job. While I am a surgeon, I am interested in pursuing all non-surgical means to the treatment of various spine conditions before considering surgical options. When surgery is decided upon, I apply the fundamentals of my training and evolving technology to maximize benefit to patients.
