Armstrong was born and raised in Aurora, Colorado, the youngest of four children to Ri and Laura Armstrong. His father was originally from Cambodia but came to the United States during the Vietnam War.
He played soccer at Rangeview High School where he was named the 2008 Denver Post All-Colorado player of the year and was a three-time All-Colorado team selection from 2007-09. He also led his club team – Rapids adidas Alliance partner, the Colorado Fusion – to the 2005 Colorado state championship.
He entered the Colorado Rapids youth system in 2007, playing with the team's U-17 and U-18 squads.
Armstrong signed a contract with the Colorado Rapids on Aug. 16, 2010. He was identified by the club as a homegrown player – an initiative established by Major League Soccer to allow clubs to develop their own youth players without exposing them to the MLS SuperDraft. Davy made his debut against Metapan in El Salvador in a 3-1 victory for Colorado Rapids, coming on as a substitute for Eddie Ababio.
