Earthworks, Inc. is a family owned business established in 1995 by Kevin Thieret, with a dream of changing and enhancing the customer stone buying experience.  His passion is still alive and well today as it was back then.  Kevin and his son Aaron work side by side every day with the over 130 employees to ensure that their vision is seen and heard by all.    


In 1997 Earthworks opened their first of 7 quarries located throughout the Midwest, as well as a state of the art manufacturing facility located in Ste Genevieve, MO.  This father and son team continues to put back into the company with several expansion efforts that allow Earthworks to provide its customers with everything from raw quarried blocks, to finished dimensional cut stones, all types of landscaping materials as well as high-quality stone veneers for both residential and commercial projects nationwide.
