After an early career on the manufacturing and distribution side, Ronald Horn decided it was time for a change and started his own fabrication business, Colorado Custom Stone. What began in 2002 as a one-man operation in a garage of a residential area, has significantly grown to a 30,000-square-foot facility in Denver, CO. Today, the company uses state-of-the-art technology, coupled with skilled workers, to output top-quality stone work. Colorado Custom Stone is proud to be an accredited member of the International Surface Fabricators Association (ISFA), Natural Stone Institute (NSI) and a NSI Accredited fabricator and installer, which means it has met or exceeded a series of skills, safety, financial and quality standards that only a select number of hard surface fabricators achieve.
