Nestled in the mountains of Northern Pennsylvania, Endless Mountain Stone Co. was founded by Robert “Bob” Coleman Sr. in 1976. Through the years, Coleman bought and sold Bluestone and accumulated quarry reserves for the future. Today, the company has reserves of over 1,500 acres of the finest quarry stone.

In 1987, Coleman pioneered the sawn and thermaled Bluestone part of the industry by installing the first “automated” bridge saw in Northeastern Pennsylvania. “This move changed the industry forever and helped shape what it is today,” said Robert “Butch” Coleman, who purchased Endless Mountain Stone Co. with his wife Donna in 1997. “We gathered more reserves and equipment from polishing to tumbling for another 25 years.”
