Trish Marsik has extensive experience supporting providers, healthcare organizations, and state and federal governments to provide quality behavioral healthcare. 

Prior to joining HMA, Trish was chief operating officer of Services for the UnderServed. In this role, she oversaw shelter/housing and clinic and ambulatory care for veterans, families, and other adults struggling with social needs and/or behavioral health challenges. She managed a diverse portfolio of behavioral health programs representing $160 million in funded services and over 1,000 personnel including homeless shelters and eviction prevention services; veterans support; clinics; assertive community treatment (ACT) teams; case management; supportive housing; residential treatment; and transitional and employment services. She also quadrupled clinic services through launching one of five NYC Certified Community Behavioral Health Centers (CCBHC) and successfully procured a federal award for additional services in the first round of federal funding. 

In her role as executive director for Mayor of New York City’s Task Force on Behavioral Health and the Criminal Justice System, Trish oversaw the implementation of the task force’s action plan which sought to better serve people with behavioral health issues in contact with the criminal justice system. She oversaw the cross-agency implementation of a 24-item mayoral-directed behavioral health and criminal justice action plan and reported progress to community stakeholders. Trish also directed the coordination of services for people identified with mental illness and a high potential for violence and integrated action plan efforts with Medicaid to leverage federal reimbursements. 

Trish previously worked in multiple capacities at the New York City Department of Health and Mental Hygiene (DOHMH). In her latest role as assistant commissioner for mental health, she managed the development, implementation, and oversight of contracted mental health programs as well as policy and programmatic initiatives. She served as the chief administrative officer for the Early Intervention Program, a multi-million-dollar federal entitlement program for children ages birth-3 with delays and disabilities. She was the director of Project Liberty, New York City’s mental health response to September 11 and directed service programs for New York City residents who were homeless, justice-involved and/or had a mental illness for organizations such as Legal Aid and the Urban Justice Center.  

Trish earned a bachelor’s degree in sociology from the University of Michigan and a master’s degree in social work from Columbia University.
