About

Bio

The single most important aspect of medicine is to understand that it is truly an art. Every patient is an individual, with different needs and different aspirations. In sports medicine, we need to tailor our care to your specific situation, whether you are a high performance professional athlete, active military, college athlete, high school athlete, club athlete, recreational athlete, or daily walker. The point is that treatment should be tailored to your specific situation. With medicine, it is also important to treat each patient with compassion. You never have to ask me what I would recommend for my own family, because I will treat you as family. I am a partner, companion, and friend in your treatment before I am a surgeon. But if you do indeed need surgery, you can be assured I will give you the best. If there is a better surgeon available to you for your particular problem, I will find him/her for you.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
