41 Doctors at The Oregon Clinic Recognized by Peers as Among the Best - 01/05/18

Portland, OR -- January 5, 2018 -- 41 doctors at The Oregon Clinic (TOC) were recognized by their peers as among the best in the region. Spanning a variety of specialties, Portland Monthly's 2018 Top Doctors list included TOC doctors in Ear, Nose and Throat; Gastroenterology; Pulmonary and Critical Care Medicine, Urogynecology, and more. With more than 200 physicians in the region, more than 20% of TOC's providers made the Portland Monthly list this year.

"Our physicians strive to be among the best in their field, and it shows," says Scot Gudger, CEO of The Oregon Clinic. "We're thrilled that so many of our physicians were honored by their peers."

For many Portlanders, the Portland Monthly list is a go-to place to find a new doctor or specialist. The magazine's annual Top Doctors project compiles a list of the city's best doctors, physician assistants, and complementary medicine providers, according to their peers. To determine the best, Portland Monthly solicits nominations from practitioners in Multnomah, Washington, and Clackamas Counties, asking what peers in each specialty they would entrust their own families care to. After tabulating nearly 18,000 votes, Portland Monthly's published list represents only the top five percent of nominees.
