Doctoral Student Clinicians

Our Clinicians

The Drexel PSC is a unique facility because our focus is on training doctoral students in state-of-the-art therapies and techniques for client care and assessment. All clinicians are closely supervised by licensed professionals affiliated with our training program. Our doctoral program is highly regarded and recruits from among the strongest applicants worldwide. As a training program, we are committed to fostering the growth of our trainees across the domains of research and practice. They learn the most up-to-date assessment and intervention protocols and receive both on-on-one and group supervision each week.

How This Impacts Your Care

There are some wonderful advantages to undergoing assessment and/or treatment at a training clinic. Our clinicians carry small caseloads and therefore, a great deal of attention can be given to your care. Our clinicians and supervisors will meet regularly and our clinicians are monitored closely as they deliver the most cutting-edge assessments and interventions available for the issues for which you are seeking care. We have a commitment to using the research available to choose, implement, and monitor the assessments and treatments that have the strongest evidence-base to address your needs. Due to the fact that we want to expose our clinicians to various assessment tools and methodologies, our clinic is not confined by cost and time for assessments the way other practices may be.


Supervision staff is comprised of clinical staff, as well as community experts.
