About Cornerstone Excavating INC
From cstoneinc.com
Your Satisfaction Is Our Priority
Cornerstone Excavating Inc. was founded in 2008 by BJ Miller, Jim Zieglowsky, Nelson Miller and Don Miller. It was our desire to form a company whose primary emphasis was on providing a quality product at a reasonable price with an unmatched commitment to customer service. After spending over 125 combined years in the construction industry we determined that we needed to create a company that is based on solid Christian principals.
