our mission
At Sunnybeam, we believe that during the preschool years, children should develop social, emotional and intellectual tools through activities that encourage them to work together, experiment, and problem solve. We create an environment that leads children to socialize with each other, make their own discoveries, and develop a love for learning.


















Inclement Weather Policy
Sunnybeam School follows the Mercer Island School District's (MISD) decisions about the closure or delay of the start of the school day due to snow or other emergency weather conditions. The MISD announcements are carried on local AM and FM radio and television stations or by checking the MISD website at www.mercerislandschools.org.
