About me

Dr. Jessica Castle joined the Harold Schnitzer Diabetes Health Center as an assistant professor in July of 2010 and is now associate professor as of January 2019. She splits her time between treating patients at the center and conducting research at OHSU. Dr. Castle sees patients with type 1 diabetes, type 2 diabetes, and general endocrine problems, such as those with thyroid or adrenal diseases. The focus of her research is treating patients with type 1 diabetes using an artificial pancreas system. Dr. Castle graduated in 2000 from University of Oregon's Robert D. Clark Honors College with a degree in biology. She has been at OHSU since 2000, when she first began medical school. She graduated medical school summa cum laude in 2004, and has subsequently completed a residency in internal medicine and a fellowship in endocrinology. She also enjoys reading, boating, hiking and spending time with her son Brandon and husband Randy.

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.
