Executive Director

Rebecca graduated from Central Michigan University with her Undergraduate Degree in Child Development and Psychology and earned her Master’s Degree in Counseling. After receiving her Master’s degree she moved to Grand Rapids and worked at the Kent County Children’s Assessment Center for 15 years.
