About me

Dr. Hostetler specializes in caring for both adults and children with allergic and immunologic conditions. She cares for patients with common diseases such as food allergies, asthma, eczema, drug allergy, chronic hives, and seasonal allergies. Dr. Hostetler is grateful for the training and mentorship she received at Duke University as a trainee and faculty member which molded her into an expert in immune deficiencies including adult survivors of pediatric immune deficiencies. She is also interested in treating immune dysregulation in the lungs. She is triple board certified in Allergy and Clinical Immunology, Internal Medicine, and Pediatrics and is excited about serving both children and adults in her home state of Oregon including Central Oregon and beyond.

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.
