Clinical Interests
My clinical interestes include pancreatic and biliary disease including gallstones, cancer, and pancreatitis; ERCP and endoscopic ultrasound
Care Philosophy
I strive to provide the best care for my patients. I believe in treating the person as a whole, taking not only disease but every aspect of a patient’s body and health, values, culture, and personality into consideration during diagnosis and treatment. I feel strongly about communicating the risks, benefits, and alternatives to treatment and having the patient be active in the discussion or decisions about his/her treatment. I believe that tests or treatment are appropriate when they make patients feel better, save or extend a life, or provide us/family with useful information. But I believe that unncessary, invasive tests or treatments that provide minimal information and do not result in improved quality of life should be avoided.
