Gerdenio "Sonny" Manuel, S.J., Ph.D.
Dr. Gerdenio "Sonny" Manuel, S.J., has practiced as a licensed psychologist in California since 1985. He completed his clinical internship and advanced clinical fellowship in inpatient and community psychology at Cambridge City Hospital, Harvard Medical School, and received his Ph.D. in clinical psychology from Duke University, his M.Div. from the Jesuit School of Theology at Berkeley, and his B.A. from the University of San Francisco.
His areas of clinical practice and scholarship include adult psychotherapy, relationships and sexuality, coping with suffering and traumatic life events, addiction and recovery, and the relationship of psychology and spirituality to human flourishing. He is the author of Living Celibacy: Healthy Pathways for Priests (Paulist Press, 2012), winner of a Catholic Press Award.
Dr. Manuel is Professor Emeritus of Psychology at the University of San Francisco, where he served as Professor and Chair of Psychology and Director of the Saint Ignatius Institute. As staff psychologist and clinical supervisor at St. Anthony's in San Francisco, he led and supervised psychotherapy groups for men struggling with addiction and recovery.
Much of his career has been spent in education and religious formation. At Santa Clara University he was the first Dean of the School of Education, Counseling Psychology, and Pastoral Ministries, Vice Provost for University Programs and Multicultural Education, and Rector of the Jesuit community; he also founded the University's Center for Multicultural Learning and co-founded its program of community-based learning in faith and justice. He taught clinical foundations in pastoral counseling at the Jesuit School of Theology in Berkeley, and has served as a trustee of Santa Clara University, Fordham University, the University of San Francisco, and Loyola Marymount University.
For the Jesuits of California and USA West, he served as Director of Vocations and Provincial Assistant for Formation — religious superior to the Jesuits in training, responsible for their studies, supervision, and readiness to advance toward ordination — and later as Prefect of Studies and Provincial Assistant for Higher Education. From 2012 to 2022 he was the Province Safety Delegate, chairing the review board on sexual misconduct and overseeing both the protocol governing allegations and investigations and the outreach and care offered to those who had been harmed. He has advised the Diocese of San Jose on mental health interventions for clergy and has published on assessment, treatment, and intervention in clergy sexual abuse.
Today he serves as Clinical Training Director at Equity Health, a federally qualified health center providing integrated primary and behavioral health care to San Francisco's diverse and underserved communities, where he trains and supervises the next generation of clinicians while continuing to teach, write, and practice.
Dr. Manuel is a therapist's therapist… He perfectly blends excellent clinical skills based in psychology, spirituality, and rich personal experience to offer clients the very best psychotherapy experience they can hope to receive.
