The Diamond Crest Service Unit is a Girl Scout organization within the Girl Scouts of Northern California Council. We serve over 2,500 registered girls and adult volunteers in Belmont, Redwood Shores, San Carlos and parts of San Mateo.

Our mission is to foster girls with courage, confidence and character who make the world a better place.

For more information on who to contact for a particular question, please click here to visit our Contact Us page.

Let us help unleash your inner G.I.R.L. (go-getter, innovator, risk-taker, leader)!

Do you have an incoming Kindergarten or First Grader (which we call "Daisies") interested in joining a Girl Scout troop in the Diamond Crest area (San Carlos, Belmont, Redwood Shores)?  If yes, please contact Cecilia Thomson. We can place older girls too!
