I’m a general gastroenterologist and treat a wide range of GI problems, but my area of specialty is in esophageal disorders.

We need to treat it to prevent patients from getting esophageal cancer. It is important to establish a level of trust and have compassion for patients, making sure they feel that I’m completely invested in what’s important for them, doing everything to get to the right answers of what’s causing their symptoms, and coming up with a plan that works best to treat their problem.

"Internship is the first year after medical school. That year, I was a real doctor, but still was supervised by the attending staff. My first attending had an international reputation but believed ferociously that the art of medicine was grounded in what he called ""the story."" Most critically, he taught me, you had to know the main character of that story -- your patient. Over years of practice, I've provided care for death row prisoners, Fortune 500 CEOs, and NFL players. Each story is unique, as should be my approach. Daily, I work on capturing the details, and I try to teach our trainees to do the same.".
