Angelina Grab

Angelina Grab joined the Board in Spring 2025. Originally from San Francisco, then Oakland, she, her family, and her community activism moved to Sonoma County in 2020. She holds a Bachelor of Arts in Political Science | Activism and Social Change (2005, NCOC), a Master of Science in Organization Development (2007, USF), and is a current Doctor of Education student in the University of San Francisco’s Organization and Leadership | Social Justice program, where she is studying public service through a critical organizational theory lens, incorporating the sociology of law. Her academic work focuses on influencing the direction of organization theory and the place of public service in fostering engagement, activism, and equitable representation of minoritized and marginalized communities. Her familiarity with the behavioral healthcare system goes beyond her previous role as Human Resources Director of a locked, residential Bay Area psychiatric facility. She has first-hand experience as a caregiver for individuals living with complex post-traumatic stress disorder and comorbidities. It is because of these experiences that she is committed to advocating for behavioral healthcare workers and to bolstering awareness of the impacts a career of caregiving and service has on behavioral healthcare workers’ lives and the lives of their family members. In her spare time, Angelina works for Sonoma County’s Human Resources Department and is a weekly volunteer at Sonoma County Wildlife Rescue, where she cares for our non-human community members.

District 4 - James Gore

Gregory Fearon

Gregory joined the Board after years of service in developing and operating homeless facility and service agencies.  Experiencing inadequate collaboration and partnerships between community agencies he led and County mental health and recovery services, he decided to pursue appointment to the Mental Health Board.  Observing inconsistent and  under-developed support for public engagement with all of the boards and commissions, he is looking forward to strengthening the abilities of all involved.  

He also has a long history of nonprofit board membership in support of the California coast, and of our redwood forests and parks.  Growing up surfing in Southern California, and learning to love our earliest civilizations, his travels have taken him to the world’s most exciting ruins and surf spots.
