“I’ve had the privilege of being introduced to NASHnal when they were vying for a job on a historic project in Chicago. They are, by far, one of the most diverse companies I’ve seen present themselves. They are intentional and honest in how they recruit talent from the C-Suite to interns. They don’t simply ‘check the box’ and it shows in their presentations. When asked to recommend companies for construction materials testing/inspection related bids, NST is the first company that comes to mind.”
