Ponessa Behavioral Health has a formal internship program for graduate students in psychology, counseling, and social work. These internships have rolling admission and are tailored to individual and corporate needs. Currently, the internship program is not APA or APPIC approved. Master’s level interns are not paid and do not receive stipends.


“Theory into Practice”

The focus of the internship program is to transition students into professional therapists by providing a protected educational environment, where they integrate classroom skills with clinical practice. This is facilitated through direct services, observations, and individual and group supervision. Interns are provided one hour of weekly individual supervision and 1.5 hours of group supervision, along with opportunities for departmental supervision and monthly specialized training.

There are internship opportunities in the general outpatient, drug and alcohol, school-based, and partial hospitalization programs. In addition, there are internship sites in Lancaster, Lebanon, York, and Harrisburg. Programs and locations are determined by hiring directors once the intern is accepted into the program. The Ponessa Behavioral Health internship program is not cohort-based. Interns can start at any time in the calendar year.

Interns videotape at least three sessions over the course of the internship and the tapes are reviewed with a supervisor to identify strengths, weaknesses, and adherence to a theoretical model. Interns also develop a caseload of 6-15 clients (depending on the program) and learn documentation skills related to therapy and case management.

Graduate students in psychology, counseling, and social work can complete the application found on this website. For additional information please contact:
