COVID-19 UPDATE The health and safety of our patients, our staff, and our families is of primary importance to us. We are closely monitoring the novel coronavirus (COVID-19) developments and following all recommendations by the Oregon Health Authority.  

If you're a current or new patient, feel free to call us for any concerns you have, and our medical assistants will return your calls Monday through Thursday from 8 am to 4:30 pm. 

We're now offering secure online video visits (Tele-Visits) which enables Dr. Mastrangelo to connect with you in a safe environment. We're also offering telephone visits without the video component if access to a computer or internet is a barrier for any of our patients. Contact our office at 541-383-2200 and we'll help you determine if a Tele-Visit is the right fit for you.


In light of the COVID-19 advancements most all insurance companies are covering tele-health options for their insured patients. If you are unsure if your insurance company will cover tele-health appointments, please reach out to them to verify coverage or contact our office.

We're also planning for the next phase of healthcare recovery where we will see patients in the clinic for examinations and schedule surgical procedures, both in the hospital and out-patient. If you have any health conditions you wish to discuss, or would like to begin making plans for a procedures, please contact our office.

As always, feel free to contact our office with any questions or concerns at 541-383-2200
