Karen Larsen, LMFT

Karen Larsen brings a rich history of public service and proven leadership to the role of the Steinberg Institute’s first Chief Executive Officer. As a natural result of her own life’s experience, her academic training, and the thirty years of recovery she has achieved, she possesses an unwavering passion and extraordinary ability to improve the lives of  California’s most vulnerable communities.

Prior to joining the Steinberg Institute, Karen served as the Director of Yolo County’s Health and Human Services Agency, an integrated agency providing social services, public health, mental health, and substance abuse services to the over 212,000 residents of Davis, W. Sacramento, Winters, and Woodland. Prior to her work at the county, Karen spent 20 years caring for uninsured, undocumented, and underserved people in community clinics and non-profit agencies. Her commitment to integrating care has not only ensured people receive the care they need but has exponentially improved the outcomes for those who have both a behavioral health challenge and other comorbid physical health conditions.  Her leadership has inspired others to build bridges across systems as a mechanism for improving outcomes between health systems, the criminal justice community, school districts, cities, and many other key stakeholder groups and organizations. This innovative model has served as a beacon that has cleared the way for the development of innumerable innovative programs with braided funding streams that maximized services for those in need across the state.

In addition to her work at the local level, Karen has been an active member of many statewide groups engaging in cross-system collaboration to address all determinants of health, including the California Welfare Directors Association and California Behavioral Health Directors Association where she co-chaired the Children’s Committee and Criminal Justice Committee. Karen also plays a leadership role on the Child Welfare Council as the co-chair of the Behavioral Health Committee; on the CalAIM Foster Care Model of Care Workgroup; and, as a member of California’s Department of Health Care Services’ Behavioral Health Stakeholder Advisory Committee. She also is a member of the California Health and Human Services Behavioral Health Task Force. 

Karen is the mother of three children and a rescue dog. She has a long-term partner, is a member of the LGBTQ community, and is a long-time resident of Sacramento. Her self-care strategies include daily walks, a gallon of water a day, and gardening.
