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.
