Boles Custom Builders, Inc. was founded by John Boles in 1989. Grounded by uncompromising integrity Boles earned a reputation for quality and fairness in the Vail Valley that it shares today. Boles expanded into markets at the Yellow Stone Club in Big Sky, Montana and Park City, UT. The business sold to longtime employee and partner Brad Foster in early 2010. In September 2011 Brad Foster changed the name of the company to Foster Construction.
