"I treat patients as if they were my own mother or father. I spend time listening, and I encourage patients to be open and honest. The best part of my job is the smiles and hugs I receive when patients get better."

His special interests include:

Compassionate Care from Experience

Fellowship-trained and with military surgeon experience, Dr. Feyen cares for your or your loved one’s digestive (GI) health with a caring hand and listening ear. “I want patients to be comfortable discussing their health needs, so I am an active listener—especially as I get to know them,” Dr. Feyen said. He enjoys getting to know people, beyond their health condition, and forming relationships.

Active Lifestyle

When not working, Dr. Feyen enjoys both playing men’s league hockey and coaching for his son’s hockey team. He, his wife and family are avid outdoor enthusiasts—and he can often be found traveling, running, walking or sledding in the winter.
