About

Bio

I am a native Oregonian. I was raised on a small hobby farm outside Banks, Oregon. I attended Willamette University in Salem, Oregon where I received a liberal arts education that prepared me well for medical school and taught me to be an independent thinker. After college I married my wife, whom I have known since high school, and then attended medical school at Oregon Health Sciences University. I graduated with honors and was initiated into the Alpha Omega Alpha National Medical Honor Society. I then pursued a career in surgery and completed my internship in general surgery at OHSU after being awarded the Outstanding Student Surgery Award as a senior medical student. However, I soon realized that I missed the longer term relationships with my patients that practice in a specialty of internal medicine could offer. Therefore, I followed my gut (pun intended) and began my training in internal medicine and then fellowship in gastroenterology. I could not be happier. Gastroenterology offers me the best of all worlds, appealing to both the technical, hands-on approach of advanced endoscopy and the personal relationships offered by caring for my patients with chronic digestive diseases that require ongoing medical care.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
