Faculty Mentors

The faculty mentors in CalSouthern’s School of Behavioral Sciences are skilled and experienced clinicians as well as dedicated, responsive and highly qualified educators.

They are available to support your learning and mastery of the course content. And, equally important, they will help you utilize the concepts you learn and apply them to resolve challenges commonly faced in clinical practice today.

CalSouthern provides instruction that enables dedicated, independent learners to gain the knowledge and skills needed to be successful in their career. The low tuition/payment structure ensures that learners graduate debt-free which is a HUGE deal in today’s world of unreasonable tuition rates and financial aid debt. I especially appreciate how CalSouthern understands that students like me, a single parent with a full-time, demanding career, may have difficulty keeping up with assignment deadlines. They are understanding and supportive and allow course extensions. I truly would not want to complete my PsyD degree anywhere else.
