Her advocacy has earned commendations from the Oklahoma House of Representatives, the Oklahoma State Senate, the City of Tulsa Mayor’s Office, the Oklahoma Department of Corrections, and 100 Black Men, among others.

Though a sought-after speaker, teacher, and community leader, Apostle Cosby remains grounded in what matters most. She cherishes her roles as mother and grandmother and often says, “My greatest accomplishment is being God’s servant.”
