Darren Nosek

Account Manager

I began my career with Dietz Supply Company as service technician in 2000. While in the service department I was essential in implementing our mobile service unit and streamlining the department to serve the client more efficiently. I am fully certified & factory trained in both powder equipment and liquid application systems. I transitioned into account management in 2006, covering the majority of the Wisconsin territory. During my tenure as an account manager, I have worked with some of the top manufacturers in my territory. I have continuously won national awards for my performance in the finishing industry. I am driven in every aspect of my life to go above and beyond, from sports, to parenting, to work, & I enjoy satisfaction of doing something the best it can be done.

I handled the service department doing repairs, equipment installations, demonstrations, I moved into sales in the late 80's and by the early 90's had my own sales area. My territory runs from the south side of Chicago down to central Illinois. I enjoy helping my customers get the most out of their finishing systems with a Hands-On approach. I have earned numerous sales awards from the manufacturers that we represent. In my spare time I enjoy flying radio-controlled airplanes and fishing.

After graduating from Milliken University, I started in the industrial spray equipment business

in March 1984.
The Dietz Family purchased the business in 1989 which was located in Addison, IL. As the business grew, we expanded the company and purchased a larger facility in Huntley, IL., and also a branch in Clearwater, FL. This month, I will be celebrating my 37th year with Dietz Supply Company. Each year I continue to learn, grow, and enjoy the business of industrial spray equipment. I hope I can lend my experience and expertise in the industry to all of my current and future customers.

Both companies have a combined seventy-five years + of extraordinary experience in the industrial finishing and fluid handling market.

Proudly joining Dietz Supply Company over #32years ago, I incorporated my previous sales success in providing our customers profitable solutions to their growing business needs. This continues to be my personal philosophy today.

Responsible for the Florida market for Dietz Supply and areas of Chicagoland, our Dietz team members have continued to support our customers in their quest to become industry leaders through ever-changing growth and service solutions. I am proud of the exceptional business we have been fortunate to create with our industry partners and customers and look forward to continued growth together. The end game for my wife and I is one day is to have the ocean at our feet, and the mountains to our back.
