Portland, OR – November 20, 2025 — Of the top-voted medical providers in the Portland metro area, ninety-six (96) are from The Oregon Clinic (TOC). Yesterday, Portland Monthly Magazine published their “Top Medical Providers” list for 2026. To develop the list, practitioners licensed by the Oregon Medical Board in Multnomah, Washington, and Clackamas Counties were asked, “If you or a loved one needed care, whom would you choose?” After tallying votes and vetting nominees, the 2026 list represents the top doctors, physician associates, nurse practitioners, and other providers across 96 medical specialties.

“As an organization, we prioritize giving patients compassionate, expert, collaborative care, no matter which of our clinics they visit,” said Dr. Richard Jamison, General Surgeon and President of The Oregon Clinic. “We take pride in being recognized and trusted by our peers in the medical field across so many different specialties.” 

TOC providers across 18 different specialties appear on Portland Monthly’s 2026 list, including Cardiology; Ear, Nose and Throat; Gastroenterology; General Surgery; Pulmonary and Critical Care Medicine; Sleep Medicine; Urology; and many more. Portland Monthly Magazine’s “Top Medical Providers” list is a trusted resource in the region for those looking to find a new doctor or specialist. Each year, thousands of Oregonians read the list and search the online database.
