Clinical Interests
I am interested in improving the health of all children with gastrointestinal problems. I have particular interest in caring for patients with pancreatitis and pancreatic disorders. I understand that these patients need complex care, so we have developed a multidisciplinary Pancreatic Diseases Program with several different specialists to improve the health and wellbeing of these children.

Care Philosophy
My goal is to improve the lives of the children I am privileged to care for. We do not need to run every test or do every procedure for every child and put them through more than is necessary. By carefully listening and understanding the story of each child, we can choose the right tests, procedures, and treatments for that particular child and their family.
