With over 15 years of specialized experience in the mental health field, Mary Hoisington possesses a comprehensive understanding and firsthand experience of the challenges faced by police officers and 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. In this role, she collaborated closely with officers to respond to 9-1-1 calls involving individuals experiencing mental illness, violent behavior, or high-risk situations.

Mary was instrumental in developing mental health co-responder programs for the Redondo Beach, Hermosa Beach, and Manhattan Beach Police Departments. These programs focused on integrating mental health expertise into law enforcement responses, and her work involved responding to radio calls and critical incidents such as SWAT call-outs, barricades, and suicide crises, collaborating as part of a team to address the needs of individuals in distress and promote the best possible outcomes.

In addition to her co-responder work, Mary’s experience extends to corrections, where she provided mental health and crisis intervention support within the Deschutes County Adult 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) Levels 1 & 2, and multiple trainings and certifications in therapy treatment modalities such as EMDR, CPT, and CBT.
