A PRN (Pro Re Nata) Counselor is a mental health professional who works on an as-needed basis, providing support and counseling services when regular staff members are unavailable. They typically work in hospitals, rehabilitation centers, or mental health facilities, assisting clients with emotional, behavioral, or substance abuse issues. PRN Counselors must be adaptable and ready to step into different roles as needed, offering therapy, crisis intervention, and support for treatment plans. Their schedules vary depending on institutional needs, making this role ideal for those seeking flexibility in their work.
