The founder, Tim Holzen, Jr, started in the heavy construction industry as a teenager, running all types of heavy equipment, laying pipe, pouring concrete, "whatever it took to get the job done right!" Still in his early 20s, Tim had accumulated so much extra evening and weekend work that in all fairness to his employer and family, he gave up his job as a superintendent for a local contractor and set out on his own. Tim recalls "with a shoestring budget, living in a shack, and a banker that trusted his word, he was on his way." Tim along with his wife, Sharon, at his side handling the bookwork, the Lord watching over them both, were able to grow exponentially through years of hard work and long hours.

T.C. Holzen grew from a one backhoe and dump truck operation to a company with a fleet of multiple excavators, dozers, loaders, and dump trucks. The company and its fleet are also supported by a modern, well equipped facility with a large mechanic shop. Over the years the company has developed the personnel, equipment, and management to handle all types of civil, commercial and industrial construction.
