Personal Statement

Whether working locally or internationally, I believe that the best medicine focuses on the patient, not the disease.  To that end, I aim to provide comprehensive surgical care for my patients, believing that informed patients can make the best decisions regarding surgery and its options.  My passion for education – for both patients and trainees – places a priority on ensuring that it is the “right surgery, for the right patient, at the right time.”
