Our corporation was founded in 1922 by Frank P. Frey. Big Rock Supply is still owned and operated by the family of Frank P. Frey. Our mission remains the same—to help contractors and do-it-yourselfers work more efficiently by providing quality products and exceptional service. With 90 years of experience, we've learned how to source almost any product and help solve almost any problem a contractor might have, at prices guaranteed to be the best!
