Bill Kiewit

I’ve been a certified arborist since 2001, with experience working for major tree services throughout the Milwaukee area. I specialize in diagnosing and treating both biotic and abiotic tree disorders. As the owner and operator of KSTC, I manage daily operations, consult directly with customers, and create customized trimming, removal, and treatment plans.

My work is driven by science and a passion for problem-solving, especially when it comes to complex or unusual tree issues. I take pride in building strong customer relationships and delivering results that improve tree health. Helping restore—or even save—a tree means a great deal to me, especially knowing how important trees are to my clients. Outside of work, I’m a husband, father of four girls, a Jiu Jitsu enthusiast, and an avid outdoorsman.
