Biography

Peter S. Theodore, PhD, is currently an associate professor with the Clinical Psychology PhD Program of the California School of Professional Psychology (CSPP) at Alliant International University, Los Angeles, the coordinator of the Clinical Health Emphasis Area for the PhD and PsyD Clinical Programs at CSPP, and a fellow of the university's Rockway Institute (a center for LGBT psychological research and public policy).

He is a licensed, practicing psychologist in the state of California whose expertise bridges the fields of HIV-prevention, LGBT affirmative therapy, substance abuse treatment and clinical health psychology. Drawing from cognitive-behavioral, strengths-focused, and existential theories, he has experience treating a myriad of mental health issues including depression, anxiety, substance abuse, trauma, sex and sexuality, and grief and bereavement.

He earned his PhD from the University of Miami in Clinical Psychology in 2005 during which time he completed an NIMH pre-doctoral fellowship in HIV/AIDS clinical research and completed his full time APA-approved clinical internship at the Long Beach Veterans Healthcare System. He has directed a methamphetamine-abuse treatment program designed specifically for gay and bisexual men, and served numerous roles on multiple federally funded projects addressing the intersection of substance abuse and HIV-prevention. His current research addresses health disparities among LGBT persons, and reducing LGBT-related prejudice, discrimination, and violence. He has presented at numerous conferences and published in journals including AIDS and Behavior, Substance Use and Misuse, Journal of Homosexuality, and Sexuality Research and Social Policy: Journal of NSRC.
