Our vibrant community is comprised of 1,075 students, 575 in our Lower/Middle School and 500 in our High School.

Student-teacher relationships are critical at GDS. To that end, we ensure that each of our students is supported through smaller classroom models and is offered plenty of time for one-on-one interaction.

GDS is located at 4200 Davenport Street in the Tenleytown neighborhood of Washington, DC.

In our Lower/Middle School, the school day runs from 8:00 a.m. - 3:00 p.m.
