Contra Costa County Seeks Applicants from District 4 for African American Holistic Wellness Hub Steering Committee 

 (Martinez, CA) – Contra Costa County is undertaking a process to develop a Feasibility Study for an African American Holistic Wellness Hub. The findings and recommendations of the Feasibility Study will provide guidance to the Board of Supervisors in their decisions regarding next steps in the development of an African American Holistic Wellness Hub for Contra Costa County. The Hub, which may include multiple sites, is intended to provide space for culturally appropriate and community-defined services that will welcome, support, heal and empower the African American community in Contra Costa County.

As part of this process, Contra Costa County will establish a 13-member ad hoc African American Holistic Wellness Hub Steering Committee to guide the Feasibility Study planning effort through a representative, inclusive, and extensive community engagement process. The Steering Committee will provide input and collaboration to County staff and the contracted Feasibility Study developer, ensuring the community voice is represented through the process and the outcomes.

We welcome applications from District 4 residents to serve on the Steering Committee. We are recruiting individuals with direct experience of system harms and inequities who are committed to eliminating racial disparities and improving outcomes for everyone, including the LGBTQ+ community, the faith community, transition-aged-youth, and the formerly incarcerated. 

The deadline to submit applications for consideration is September 28, 2023. Applications will be considered by the Board of Supervisors Equity Committee composed of Supervisors Federal Glover and John Gioia.  To submit online applications, an application form is available at: https://www.contracosta.ca.gov/DocumentCenter/View/6433/. Applications can also be emailed to [email protected] or mailed to the Clerk of the Office of the Board of Supervisors at 1025 Escobar Street, 1st Floor, Martinez, CA 94553.
