My approach to treating patients:
Whether you’re making the decision for orthopaedic care, or would just like to expand your knowledge, I hope this site helps you become informed and more confident about the incredible realm of orthopaedic treatments available.

I believe in meeting patients’ individual needs through comprehensive evaluation and treatment designed to help them achieve an active, pain-free lifestyle. Many musculoskeletal conditions can be treated by non-surgical techniques–surgery is just one treatment option. I combine leading edge techniques with proven traditional methods to provide our patients with the best orthopaedic care possible.

It is my responsibility to make sure patients are well informed about their conditions and the multiple choices of treamtent. My professional staff and I will also provide you with the patient education materials that give you added appreciation of your condition and treatment options.
