Our Coaches

Geoff Schaefer
Head Swim Coach

Tel: 301-928-0305
Coach Schaefer has been with the Sun Devils since the summer of 2000. In his 19 years the accolades are strong as they stem from Washington Post and Montgomery Gazette Coach of the Year to Division E titles, but the element where he hangs his hat is the one win in Division A during the summer of 2017. He has seen over 2000 swimmers and divers go through the CG system and treats all of his athletes and parents as his own family. Geoff teaches English at Walt Whitman High in Bethesda and recently retired from coaching high school swimming and volleyball so he could raise his two daughters better. He looks forward to the Saturday morning theme execution, Friday night pep rallies and the B meets that take less than two hours! PASL for life!!!
Thomas Shinholser
Head Dive Coach


Thomas is a rising senior at Virginia Tech and is a business major. He has been diving for Virginia Tech throughout his time there and is a Conference Medalist and NCAA All-American. Thomas was the Country Glen diving coach two summers ago when the Sun Devils went undefeated in the dual meet season and were divisional champs. Last summer he stayed at school to compete at the Olympic trials in Indianapolis. He is excited to see familiar faces and hopefully a lot of new ones too.
