Biography & Education

I believe all surgeons should have two essential qualities; integrity and empathy. To me, integrity means treating each patient as if I were caring for my wife and children. Family is exceedingly important to me so you can be assured you will be well cared for. I will not recommend surgery unless all non-operative solutions have been explored and exhausted. Empathy is a term not often associated with surgeons. This is quite unfortunate, because we are in the ideal position to support patients as they recover from difficult procedures. In my practice, your questions will be heard and answered promptly. By working together, focused on your goals, we can optimize the patient experience and maximize your health and well being.
