Welcome to the Dexter-Southfield Summer Camps Day and Overnight - Hockey… sailing… swimming… arts and crafts… rockets… and much, much more! Day Programs on the Brookline campus provide a wide range of age-appropriate camps—from three-and-a-half-year-old children to students entering grade 10—such as Day Camp, Hockey Camp, Enrichment Camp and Science and Technology Camp. On the Cape Cod campus, students entering grades five through ten have a blast in the week-long, overnight Marine Science and Sailing camps.
