Meet Our Team

The Gastric (stomach) and Esophageal Cancer Program has a multidisciplinary team of physicians from multiple specialties to give our patients the most comprehensive treatment available.

Patients with suspected or diagnosed tumors related to these organ systems can often be evaluated by general surgeons, gastroenterologists, medical oncologists, radiation oncologists and interventional radiologists quickly. Each member of this team brings a special expertise. The coordinated efforts allow for a well thought-out and streamlined diagnostic and treatment plan.
