About me

Dr. Messer specializes in treating infections in organ and bone marrow transplant recipients, HIV patients and infections in the general population. Dr. Messer also has a particular interest in tropical diseases and studies viral diseases transmitted by mosquitoes. Dr. Messer finds working with vulnerable populations – those that are immunocompromised or living in the developing world - particularly challenging but also uniquely rewarding.

Dr. Messer enjoys spending time with his family, including his wife who is an epidemiologist and professor at Portland State University and his three teenage daughters. He is an avid alpine and backcountry skier and he and his wife enjoy running and cycling together. He takes a serious, but safely distant, interest in all of his daughters’ sports and academic activities. His creative outlets include photography and woodworking.

Before scheduling your appointment, we recommend you contact your insurance company to verify that the OHSU Health location or provider you plan to visit is included in your network. Your insurance company will also be able to inform you of any copayments, co–insurance, or deductibles that will be your responsibility. If you proceed in scheduling an appointment and your health insurance benefits do not participate with OHSU providers, your out of pocket liability may be higher.
