Maresa Talbert is also co-founder and Chief Executive Officer of The Justice Workshop (TJW), a nonprofit organization that helps grassroots individuals embrace their political power through education and community organizing.

Placed on the November 2020 ballot, the charter amendment passed with the approval of nearly 75% of the voters. The newly formed Commission seeks to strengthen community oversight of complaints against the police, as well as the policies, procedures, and practices of the San Diego Police Department.
