As he was growing up, Derek helped his father in his vocation as an auto mechanic. “I found that I was drawn to repairing mechanical devices, and I decided to pursue it further after attending college.” In his current position at ADS, Derek gets to service a wide range of equipment. “To maintain and repair the equipment, you have to be skilled in multiple areas—mechanical, electrical, hydraulic, pneumatic, etc. I like the challenge of using all of those skills.”

Did you know …
Derek loves spending time in his “man cave,” also known as his “shop.” (You can’t really call it a “workshop” because not much “work” goes on in there.) Derek tinkers with his babies—a 2000 Corvette and a classic 1979 Trans Am—changing the oil and washing and waxing them. And, sometimes, Derek puts out the extra effort and just sits back and admires them.

Little-known fact
Derek has been known to stray from his comfort zone and occasionally eat salad.

Call Derek when …
Your dock equipment or doors need maintenance, repairs, or upgrades. Derek also performs dock and door audits.
