Summer Tinkering is an immersive, five-day building experience that introduces students to real tools and focuses on designing and building large-scale creations out of wood, with each week beginning with a surprise theme such as Harry Potter or Pirates. Mountain Camp Marin is a K–8 day camp that focuses on outdoor fun, creativity, personal growth, social-emotional learning in a tech-free environment, and camper choice in activities. Early Learners is a developmentally-appropriate day camp for incoming Kindergarteners that introduces them to their new school and future classmates through indoor and outdoor play, art projects, and singing and dancing with teachers and interns.

Summer Tinkering springs out of Mark Day School’s long-standing collaboration with the Tinkering School in San Francisco, and Mountain Camp Marin builds on a three-year research study with the Stanford Graduate School of Education on the beneficial impacts of the camp experience on child development. For more than 20 years, Mark Day School has offered a summer program specifically designed for incoming Kindergarteners. The school community is founded on diversity, inclusivity, and lifelong learning, with a 7:1 student-teacher ratio, 36% of students identified as students of color, and teachers averaging 22 years of teaching experience.

Summer Tinkering lead instructors are David St. Martin and Tatian Greenleaf, Mountain Camp Marin’s Camp Director is Mario Del Cueto, the Early Learners lead instructor is Lisa Becker, and the Director of Extended Day and Summer Programs is Savannah Guinn. Families and community members describe Mark Day School as a place where students are supported from Kindergarten through 8th grade, where teachers greet students warmly, and where connections with teachers and peers are valued.
