Hello, my name is Wade Duncan and I’ve had the privilege to be at Les Mack Automotive for the past 27 years. I enjoy working with customers and helping them with all of their automotive needs. I strive to work my hardest, putting my personal passion for helping people to the test on every deal. I have lived in Lancaster all of my life along with my wife, Robin. We have been blessed to raise 3 beautiful children, Taylor, Paige and Blake. My new passion in life is spending time with my Grandson Asher, he brings out the best in me and is a great reminder of how great life truly is. When not working, I enjoy spending time with my family, going on the river and watching my favorite sports teams. I look forward to getting to know you as I work with you to find the right vehicle and provide a smooth purchase process. Please feel free to call me on your next vehicle purchase or check us out online at lesmack.com. Where you always get more from Les……and Wade!

Hello, my name is Steven Jantzen. I just started with the Les Mack Team in March of 2018. I have been in automotive sales for a year now and I have enjoyed every second of it! I am very excited to get to know the Lancaster community and all that it has to offer. I believe in getting to know each one of my customers as well as creating long-lasting relationships with them. I was born in Platteville and graduated from Platteville High School. I have two beautiful children Alivia, (6) and Levi (1). Alivia attends St. Clement School in Lancaster and Levi is still in daycare. We just built a home outside of Potosi. We enjoy taking Ranger rides down the backroads and on our trails. I am also an avid deer hunter. I am thrilled to join the great team here at Les Mack. I look forward to many years of putting dreams in driveways. Please don’t hesitate to give me a call for your next vehicle purchase or if you have any questions at all!
