Professional Background:
Eric earned his Bachelor of Architecture from Virginia Tech in 1993, then moved to Denver, CO, where he gained valuable field experience as a carpenter and residential framer. He later worked as an assistant project manager for a residential developer in Parker, CO until 1997. Following a tour of Europe in the summer of 1997, Eric moved to the Roaring Fork Valley and spent 12 years working with two award-winning architecture firms, refining his design skills, and his eye for detail. Although he enjoyed collaborating on, and developing design concepts, his passion for construction management led him to transition to residential construction in 2008.

Outside of work:

Away from work, Eric loves hiking, skiing and traveling with his family. You might also, on occasion, find him biking, golfing, or playing ice hockey.
