Mary Hoisington, LMFT
With over 15 years of clinical and assessment experience, Mary Hoisington has a comprehensive understanding and firsthand experience of the challenges faced by first responders. Originally born and raised in the Seattle area, she honed her expertise during more than a decade in Los Angeles County, where she gained diverse experience, including serving as a mental health co-responder with the Los Angeles Police Department.
Mary was instrumental in developing mental health co-responder programs for the Redondo Beach, Hermosa Beach, and Manhattan Beach Police Departments. Her work involved responding to radio calls and critical incidents involving mentally ill, violent, or high-risk individuals, including SWAT call-outs, barricades, and suicide crises.
In addition to her co-responder work, Mary’s experience extends to corrections, where she provided crisis intervention, assessment, and mental health support within a county jail. Her commitment to professional development is reflected in certifications as a Law Enforcement Academy Instructor through the LAPD, completion of the FBI’s Level 1 Crisis Negotiation Training, Critical Incident Stress Management (CISM I & II), and evidence-based practices including EMDR, CPT, and CBT.
Mary also maintains a private therapy practice, separate from her evaluation work, where she serves adults and first responders.
