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. Visit the billing and insurance section of our site for more information.


Dr. Harmon specializes in caring for women with high risk pregnancies. He has specialized training in fetal diagnosis using ultrasound, as well as dealing with complex medical conditions during pregnancy. Dr. Harmon enjoys spending time with and forming lasting relationships with his patients in order to better understand their needs during this vital time.

His philosophy on pregnancy is centered around shared decision making with patient’s and families. By providing counseling, knowledge, and treatment options, Dr. Harmon hopes to empower women to make informed decisions regarding their healthcare and birth experience.
