The Hillburn Granite Company has been in operation in various forms for over 250 years. In its most recent renewal as of 2011, owner LeeAnn Matthews along with husband Kristian Matthews began the company to provide high quality granite to the building trades. While Mrs. Matthews oversees day to day operations of the business, Kristian's education in architectural stonework from St. John the Devine Cathedral Stoneworks NYC and Bath College Architectural Stone Program in Bath, England has allowed the company to develop a niche in the dimension stone industry. LeeAnn and Kristian Matthews also bring 20 years of experience running Legacy Stoneworks, a leading architectural stone consulting company.

The Stone

Hillburn Granite™ has been specified for important architectural projects around the New York City area for over 250 years. Early uses of the stone included bridge abutments and train trestles for the Erie-Lackawanna railway as well as for monuments in and around New York City. It was one of the primary architectural stones used on original homes, walls and landscape features in Tuxedo Park, NY when it was constructed in the late 1880's by famed architect Bruce Price and Landscape architect Ernest Bowditch. In more recent years Hillburn Granite™ was specified and used on "The Stone Mansion" - Alpine, NJ - and on other significant residential and commercial architectural projects on the East Coast.
