Term Expires November 2029
Clark, his wife Sallie, and their three children have called Castle Pines home since 2013. Their kids all attend Douglas County Schools, and Sallie serves in the district as a learning specialist. A lifelong educator, Clark began his career just outside New York City, teaching math and business at a public high school. He went on to earn a Master’s in Educational Leadership from Columbia University and an MBA from Fairfield University. Clark later became the principal of the same school where he first started teaching. When Clark and Sallie moved back home to Colorado in 2013, he took on a turnaround role as principal of one of Denver’s lowest-performing alternative high schools. Working alongside a dedicated team of educators, he helped transform it into one of the highest-performing alternative education campuses in the city. As enrollment grew, Clark led the opening of a second campus and now serves as Executive Director of the organization. Outside of work, you’ll find Clark enjoying a medium-rare cheeseburger with his family on Friday nights or sampling Sallie’s famous soft, chewy chocolate chip cookies. He also loves running, hiking, skiing, knitting, reading, and painting.
