In November 2017, Leslie joined the CASA staff.

During Leslie’s first year at CASA of Montgomery County, and in addition to her case supervisor work, she became the staff contact for sexual exploitation advocacy. Leslie believes that CASA has a dual role in ending the sexual exploitation of children in Montgomery County by serving children at risk of becoming victims and working with recovered victims. Her anti-trafficking initiative involves preventive education, raising awareness, reporting, and collaborating with government, law enforcement, and other child welfare nonprofit agencies.

In November 2018, Leslie took on the role of Collaborative Family Engagement Facilitator for the CASA of Montgomery County office. She is passionate in her belief that CPS, CASA, and the families and friends of children in foster care can work together to build a support system for those children and parents.
