“As an alumna, parent and trustee, CGPS has meant so much to me. I feel tremendous pride in returning as an adult to the School that made me who I am today. As a student, I felt supported and encouraged. Finally, as a parent who has the privilege to serve as a trustee, it is a pleasure to watch all three of my children's personal interests, strengths, and passions nurtured and celebrated."
