I grew up in Spokane, Washington and went to Eastern Washington University for undergrad and studied Biology and Chemistry. I went to medical school at Pacific Northwest University in Yakima, Washington. I spent six years in Michigan State University where I studied Internal Medicine and specialized in Gastroenterology. I am married with two boys. We love to spend as much time outside as possible with activities such as walking, riding bikes, playing outdoor games, traveling and experiencing new places and cultures. I also love golfing and fishing.

What is a Gastroenterologist?

A Gastroenterologist is a physician with dedicated training management of diseases of the gastrointestinal tract and liver.


A Gastroenterologist must first complete a three-year Internal Medicine residency and is then eligible for additional specialized training (fellowship) in Gastroenterology. This fellowship is generally 2-3 years.

Gastroenterology fellowship training is an intense, rigorous program where future Gastroenterologists learn directly from experts in the field and develop a detailed understanding of gastrointestinal diseases. They learn how to evaluate patients with gastrointestinal complaints, treat a broad range of conditions, and provide recommendations to maintain health and prevent disease. They learn to care for patients in the office as well as in the hospital.

The most critical emphasis during the training period is attention to detail and incorporation of their comprehensive knowledge of the entire gastrointestinal tract to provide the highest quality endoscopy and consultative services. The final product is a highly trained specialist with a unique combination of broad scientific knowledge, general Internal Medicine training, superior endoscopic skills and experience, and the ability to integrate these elements to provide optimal health care for patients.
