Monica Martinez

CASA Program Director

Monica Martinez is honored to serve as the Program Director for CASA of Mariposa County. She began her work at CASA in 2016 and has continued to be actively involved in the development and growth of CASA’s programs. Monica started on the team that created the RECESS program from the ground up. Her passion to support children and their families helped RECESS to grow into a dynamic, successful resource for the Mariposa community. Her persistence and work ethic lead to a promotion as CASA’s Program Coordinator. In this role, Monica combined her knowledge of the needs of families with advocating for children in Mariposa’s foster and delinquency systems. Working with Volunteer Advocates, community partners, and children in foster care strengthened her sense of commitment to provide quality, direct services to the youth CASA supports. Now as CASA’s Program Director, Monica is using her wisdom and experiences to instill these values in all of CASA’s programs.  Monica resides in Mariposa with her husband and four children. She counts her children among her greatest accomplishments.  Monica enjoys spending quality time with her family, whether it be at sporting events with her kids or enjoying a nice day out and about in beautiful Mariposa. She is excited about the work that CASA is doing and is looking forward to innovations and progress yet to come.
