Meet the Executives

Randall J. St. Antoine


Randy has had a successful career in the building industry since 1975. He began as a drywall hanger, and rapidly gained expertise as a specialty contractor employee, eventually running projects as a foreman. He moved from Wisconsin to the Denver area in 1980 and accepted a position with a large local drywall company, and quickly advanced from a foreman to a superintendent, responsible for large commercial drywall projects. In 1993, he was promoted to the position of Field Operations Manager and successfully expanded operations to form a Mountain Division in 1995, which provided that region with a major commercial drywall contractor. In 2003, Randy returned to the Front Range area to become General Superintendent for large commercial projects until 2006 when he seized the opportunity to become General Superintendent, and later advanced into the position of Vice President of Field Operations. Randy’s focus was to transform a marginal multi-family operation into a very profitable enterprise. In 2014, he resigned and decided to use the expertise he had acquired over three decades to form his own company. Randy’s goal is to mold RDS into a preeminent leader in the drywall industry, providing comprehensive services for both commercial and large multi-family projects.

Randy’s passion is trophy fishing. He and his wife also enjoy their newly discovered hobby of collecting gemstones and driftwood, and practicing their lapidary capabilities.
