Mark Day School Summer Programs

Mark Day School’s summer lineup is organized as three separate daytime programs. Summer Tinkering runs in week-long sessions built around a surprise theme. Campers ages 7–13 design and construct large-scale projects from wood while using real tools. The program is student-centered and asks participants to experiment, learn from mistakes, build collaboratively, and stretch beyond their usual effort under the guidance of Mark Day faculty and staff.

Mountain Camp Marin serves rising kindergarten through eighth grade. Campers are grouped largely by school grade, and activity offerings rotate from week to week while core Badge Program activities remain consistent so returning campers can continue building skills. The program emphasizes outdoor fun, creativity, personal growth, a tech-free environment, and opportunities for campers to choose activities during the day. Early Learners is a separate program for incoming Mark Day kindergarteners. Led by teacher Lisa Becker with other Mark Day teachers and interns, it uses indoor and outdoor play, art projects, singing, dancing, and school routines to help children become familiar with the campus and future classmates. Families may enroll in multiple Early Learners weeks, with scheduling flexibility described by the school.

For Mountain Camp Marin, two snacks are provided each day as part of camp tuition. Families may also order a catered lunch for an additional fee before the weekly ordering deadline. Campers who do not purchase the lunch plan should arrive with an adequate packed lunch each day. The program states that it can accommodate some common food allergies and asks families with specific allergy questions to contact the camp office. The saved official sources do not describe meal arrangements for Summer Tinkering or Early Learners, so these details should be read as Mountain Camp Marin information only.

Mountain Camp Marin publishes several practical rules for daily supervision and pickup. An authorized person other than a legal guardian may pick up a camper when they have the camp’s Day Camper Pick-Up Placard. Families are asked to submit a Camper Adjustment Request Form when a child will arrive late, leave early, or miss a day so staff can prepare. The packing guidance requires closed-toed shoes, recommends sunscreen and a reusable water bottle, and asks swimming participants to bring appropriate pool gear. The program also describes a tech-free environment and asks campers to leave electronic devices at home. These published procedures are specific to Mountain Camp Marin; the saved sources do not provide equivalent safety procedures for Summer Tinkering or Early Learners.

Summer Tinkering is led by Tatian Greenleaf and David St. Martin and is described as operating under the guidance of caring, experienced Mark Day faculty and staff. Mountain Camp Marin lists Mario Del Cueto as camp director. Early Learners is led by Mark Day teacher Lisa Becker with other Mark Day teachers and interns. The saved official sources identify these leaders and staff groups but do not publish a staff-to-camper ratio or a general set of staff credentials for all three summer programs.

Mountain Camp Marin says email is its primary parent communication channel during camp, with text messages also used for reminders and updates. Families who need to reach a child during the camp day can call the camp office. The program also posts updates through its social media channels. The saved official sources do not describe an equivalent during-camp communication process for Summer Tinkering or Early Learners.

Mountain Camp Marin offers optional extended care before and after the regular camp day, with a separate extended period for younger Cub Camp participants. Families may authorize another pickup person by using the Day Camper Pick-Up Placard. Late arrival, early pickup, or a missed day should be reported through the Camper Adjustment Request Form. Campers are asked to bring a reusable water bottle, closed-toed shoes, and sunscreen; those planning to swim should also bring a swimsuit, towel, and suitable goggles. A packed lunch is needed when the optional catered lunch plan is not purchased. The saved sources do not publish comparable logistics for the other Mark Day summer offerings.
