Glen Lewis Stimmel


Glen L. Stimmel, a USC faculty member since 1974, served as Interim Dean of the USC School of Pharmacy and the John Stauffer Dean's Chair in Pharmaceutical Sciences in 2015-2016. He is a professor of Clinical Pharmacy, Psychiatry and the Behavioral Sciences in the School of Pharmacy and the Keck School of Medicine, and since 2016 serves as the Associate Dean of Academic Affairs.

Stimmel has long been a national voice in expanding the scope of practice for pharmacists, including advocacy for pharmacist prescriptive authority. He led a pivotal pilot project in the late 1970s that was one of only two funded statewide to examine the safety and efficacy of pharmacists serving as prescribers. The successes of more than 30 pharmacist prescribers in this pilot program -- practicing in a wide variety of healthcare settings -- led to passage of legislation in California allowing pharmacists to initiate and modify drug treatment, order lab tests, perform physical assessments and administer drugs under physician authority. This law set the stage for further expansion of pharmacist authority passed in California in 1983 and, ultimately, 2013’s Senate Bill 493, which recognizes pharmacists as healthcare providers.

Throughout his career, Stimmel has published numerous studies and opinion pieces in a range of journals supporting the expanded practice role for pharmacists. His clinical work has focused on psychiatric pharmacy, as well as maintaining a longstanding practice in geriatrics and rheumatology at the LAC+USC Primary Care Clinics. Stimmel has long been a prolific scholar in the field, having published over 230 articles and textbook chapters and pioneered efforts in developing psychiatric pharmacy practice, education and residency programs.

He is a founding member and past president of the College of Psychiatric and Neurologic Pharmacists and of the American College of Clinical Pharmacy, where he is also an elected fellow. He is an original member and past chair of the Board of Pharmaceutical Specialties Council on Psychiatric Pharmacy Practice, a past board member of the American Association of Colleges of Pharmacy, and a past vice chair of the American Association of Health-system Pharmacists Commission on Therapeutics. He is one of only two pharmacists ever elected to membership in the World Association for Sexual Health, and also holds membership in the Sexual Medicine Society of North America and the International Society for Sexual Medicine. In the School of Pharmacy and Keck School of Medicine, Stimmel regularly teaches topics of depressive disorders, counseling patients about medication, and sexual medicine.

The College of Psychiatric and Neurologic Pharmacists (CPNP) Foundation selected Dr. Stimmel as the recipient of its 2016 Career Achievement Award, one of the highest honors recognizing outstanding, sustained contributions that advance and expand psychiatric or neurologic pharmacy.

Stimmel earned his Doctor of Pharmacy degree from the University of California-San Francisco (UCSF), after which he completed a pharmacy residency in psychiatry at the Langley Porter Neuropsychiatric Institute of the UCSF Hospitals and Clinics in San Francisco. Before joining USC, he was an assistant professor at UCSF and served as the first clinical pharmacist for the District V Mental Health Center in San Francisco, where he helped define the pharmacist's role on the healthcare team in a mental health setting.
