Portland, OR – November 22, 2022 — Seventy-five providers at The Oregon Clinic (TOC) were named to Portland Monthly Magazine’s annual “Top Medical Providers” list, recognized by their peers as among the best in the region. In Portland Monthly’s annual peer survey, medical providers identify which colleagues they would turn to if they needed specialized health care.

Spanning a variety of specialties, the 2023 list includes TOC providers in Gastroenterology; Colon and Rectal Surgery; General Surgery; Neurological Surgery; Obstetrics and Gynecology; Pulmonary and Critical Care Medicine; Sleep Medicine; Urogynecology; Urology; and more.

“We are honored to see so many of our physicians recognized each year by their peers,” said Dr. Richard Jamison, President of The Oregon Clinic. “We appreciate the trust our fellow physicians put in us.”

For many in the Portland metro area, Portland Monthly’s database is a go-to place to find a new provider or specialist. The magazine’s database compiles a peer-vetted list of the Portland area’s very best doctors and other providers. Portland Monthly solicits peer nominations from every licensed doctor, physician assistant, and registered nurse in Multnomah, Washington, and Clackamas Counties.
