Meet the Staff

We are staffed by highly trained professionals who have many years of experience working in the University setting. We are committed to helping students, faculty, and staff with any concerns that may require professional counseling and psychiatric services.

***Requesting to work with a specific counselor may mean a significantly longer wait time for services to get started depending on that counselor's current case load.

Providing counseling services has been the focus of both my training and career as a psychologist.
