Clinical Services

John Hamel provides individual, couples, family and group counseling and psychotherapy to a wide variety of clients.  His specialized clinical services include a substance abuse relapse prevention group, family violence assessments (including specialized assessments in disputed-child custody cases), victim services and advocacy (including victim support groups), and treatment programs for angry and violent men, women, couples, parents and teens.  Although many of his clients are voluntary participants, many are referred from Family Court or Child Protective Services, or mandated by the courts to participate in either a batterer treatment program, or a parenting program.  These programs are available at several locations in the Greater San Francisco Bay Area, California, USA, including in San Francisco, Walnut Creek, San Rafael, Berkeley, Oakland and Vallejo.  A current group schedule can be found at his website,

Mr. Hamel also provides consultation and training for mental health professionals, batterer intervention providers, shelter workers and victim advocates, court mediators and evaluators, teachers, attorneys and law enforcement; and speaks regularly at domestic violence conferences around the country.  He is a pioneer in the development of the evidence-based, gender-inclusive approach to domestic violence, a newly-emerging, empirically-based model of research and treatment.  His trainings been praised both for their innovative look at theory and policy, as well as their abundance of practical, hands-on intervention tools.  Additionally, Mr. Hamel serves as an expert court witness on the subject of family violence, and has testified before the California Legislature on domestic violence public policy.


Currently, Mr. Hamel is working on a manuscript with Gregory Stuart, Ph.D., and colleagues that reports on a study of motivation for physical abuse perpetration in a dating population.

He is also collaborating with Fred Buttell, Ph.D., on an outcome study of batterer intervention programs in Alameda County, California.

Two manuscripts are currently under review for publication in peer reviewed journals.  One reports on a new measure of emotional abuse and control, the Controlling and Abusive Tactics questionnaire (CAT); the other provides an overview of evidence-based research on domestic violence intervention programs.
