Excalibur is sponsoring a table at the upcoming Stone Cove “Do Good Things Sunday” event on September 29th where proceeds go to support charity, The Nature Generation (NatGen). NatGen’s programs help close the environmental literacy gap in underserved youth. Excalibur has in the past supported efforts to donate environmental books to DC’s Charles Hart Middle School and sponsor a hands-on field trip for students with NatGen. Excalibur encourages local professionals to come to the event in Herndon, VA.
