"I created a firm that tries to be practical and knowledgeable about the testing business, the construction processes in which we are involved, and the long term performance implications of our tests and observations.
This starts by having me being readily accessible in person or by cell phone to both my employees and our clients in solving problems…and continues with having experienced personnel at all locations. We strive to be approachable – so that potential problems are identified early."
-Colby Verdegan, CEO
