Visit with pediatric specialists from hospitals in Portland, hosted by COPA pediatrics in Bend

Visiting Pediatric Specialists

Visiting Pediatric Specialists

Sometimes children have medical conditions requiring diagnosis and treatment by pediatricians with specialized training and deep experience in focused areas of medicine. Most pediatric specialists in Oregon practice in Portland at one of several children’s hospitals, which can be a burden on local families who must travel for their visits.

To help our patients and keep families at home, COPA partners with Portland hospitals, Randall Children’s Hospital at Legacy Emanuel and Doernbecher Children’s Hospital at OHSU. As a result of our hosting relationship, the specialists listed below travel at regular intervals to Bend to see patients at COPA’s Northwest Crossing location.

If you would like to schedule an appointment with these physicians, please call the phone number for that physician at their Portland medical office. COPA does not schedule appointments for these providers, however, our physicians may refer a patient to a specialist below, based on the patient’s medical needs.
