- General Manager
I have spent the majority of my life in the car business! Started in the detail department while in Junior High, then on to selling cars in 1983. From there I worked my way up to the business office and spent several years doing that. My next stop was as a sales manager and now I am the acting general manager. I've been married to my wife since 1983, the same year I started in sales!  We have 3 wonderful kids and 5 grand kids (so far!) On our spare time we love to travel, camp, and play golf for relaxation. I look forward to assisting you on your next visit!

Born and raised in the area, I have been in automotive sales since 2017. In 2020 I was a GMC 'Mark or Excellence' award winner for superior sales volume and customer satisfaction. I am very family oriented and customer service driven, both demonstrated by a high client family and friend referral rate. I enjoy hunting, boating, cooking and snowmobiling with Joy, my wife of 25 plus years, two boys (Jacob-23, Johnathon-18), friends and a large extended family. My friendly, low key and trustworthy personality makes the sales process comfortable, and like my current customers you'll be back time and time again for a family style vehicle buying experience! I look forward to assisting you on your next vehicle transaction!
