In 2006 Williams created the Kellie Williams Program  in the Washington D.C. area. The program will provide Washington, DC students between the ages of 14-20 an opportunity to produce a television show to air on Comcast Cable Local On-Demand. She stated, "I wanted to create a program similar to the one I grew up with (Howard University Children's Theatre). I wanted to bring it to the masses, not to just people who were familiar with the arts but to people who had never experienced any art". She has a younger sister and brother named Marti and Donte, respectively. Williams married Hannibal Jackson on September 5, 2009. They have two children.
