Why did you choose to specialize in Gastroenterology?

Gastroenterology is a field of medicine I have been able to immerse myself into. It is a field that is ever changing with technology. I enjoy working with my patients in offering multiple options regarding their care. It is a field in which I am able to truly affect my patients’ lives both short term and long term. Developing a plan involving the patient is an effective approach in the patient’s treatment outcome. I am someone who believes that it is my job to educate the patient and let them make an empowered decision about their care.

I enjoy performing upper endoscopy, colonoscopy, and ERCPs. I like to offer additional options to my patients such as high resolution esophageal manometry, pH testing, and video capsule endoscopy.
