She is the Elective Department Head and a member of the teacher Leadership Team. 

Along with Ms.Thornton, she also directs the CMS Spring Musical. Students from all grades are invited to audition for on-stage roles in the performance, or apply for positions on the backstage crew.

She has a daughter, Jillian, who is in the 11th grade at CHS and they live in Cartersville with her husband, Gavin, and two cats, Luna Lovegood and Lexa. She is a fan of all things Harry Potter, musical theatre, too many TV shows to list, UGA, KSU, NASCAR and the Braves.
