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.


Dara is a physician assistant in the Department of Neurological Surgery and works closely with the skull base team.

Physicians assisitants (PAs) are often referred to as mid-level providers. Physician assistants are highly trained members of our neurological surgery health care team who practice medicine with the supervision of licensed physicians, providing patients with a wide range of services that would otherwise be performed by physicians. Specific duties are defined by state regulation and practice setting, but include a variety of both diagnostic and therapeutic procedures. Utilizing a medical model of patient care, PAs are trained to obtain medical histories, perform complete physical examinations and minor surgical procedures, diagnose illnesses, order and interpret routine diagnostic tests, develop treatment and management plans, suture wounds, set fractures, assist in surgery, and provide education to patients regarding illness, health promotion and disease prevention.

Dara works directly with Drs. Delashaw, Dogan and Coppa in their respective neurosurgical clinics. Visit the Department of Neurological Surgery's website for information about academics, conferences, residency and fellowships.
