Surgery can be a daunting decision for many patients. We at Stony Brook are committed to providing patients with the best care available. By providing them with timely information about their condition, and possible interventions, our team approach is sure to address our patients' surgical needs. My expertise is in general emergency surgery, hernias, endoscopy, and other elective procedures. I have over 7 years of experience in rural surgery and over a year's experience at Shouldice Hospital performing more than 650 hernias (the typical surgeon would perform an average of 30-50 per year). I enjoy a systems approach to the delivery of healthcare, and am committed to its improved quality and efficiency. I believe there is always a better way to do things.
