Since joining Cornerstone, Matt’s engineering experience can be best described as cross-functional. He has been a major player in the design of sign structural components and foundations as well as large, complicated displays and scoreboards. Matt’s primary focus, however, is serving as the point of contact for Cornerstone’s residential and local structural consultations. He is the go-to for house beams, retaining walls, structural observations and most other industrial or residential structural needs. Matt graduated from Tennessee Tech in 2004 (B.S.C.E.) and has proudly served Cornerstone ever since. He is a member of the ASCE.

Mark’s experience in the engineering-related field began in 1980, working in various positions within nuclear power. Since then, he has been involved in a wide array of roles including leading installation teams, quality control, and testing and implementation before he settled into civil design and drafting. Mark’s experience with the latest in civil engineering software is his strongest suit. In fact, he has provided training and technical support to several civil engineering firms across East Tennessee on the implementation of cutting-edge software. At Cornerstone, Mark utilizes this knowledge to provide fantastic civil design services. The software knowledge coupled with his years of experience and contacts make Mark a highly-valued asset at Cornerstone.
