    My name is William Dierks. I am originally from Havertown, Pennsylvania and currently live in Waukegan, IL. I attended William Jewell College in Liberty, Missouri and am a U.S. Army/Vietnam Veteran. I am married, have two children and three Grandchildren. My wife is Vet Tech at a local Animal Hospital, so yes, we have two dogs and several cats.

    I serve on the Vestry at Christ Episcopal Church in Waukegan. I volunteer as a server at the Community Meal several times a month and act as a Greeter and Usher at Sunday services. I was in the Golf Business for many years, having worked for Marriott, Indian Lakes, Midlane Country Club and Westmoreland Country Club before coming to work at Knauz.

    My current job title is Sales Consultant at our Hyundai & Genesis Store. I assist our customers in meeting their needs whether it be a new or pre-owned vehicle. One of my strong suits is getting to know my customers so that I can match their needs with a vehicle.

    I am Star Certified with both Hyundai and Genesis.

    To contact me please email me at or my direct line is 847-283-8204.
