The president, Mindy Nowakowski, leads the company at Eco Lighting Services and Technology, LLC (ELS-T). She enjoys making customers aware of "our specialty" = making customers happy and saving them money. Whether upgrading your lighting and/or controls, electrical needs, small tenant build outs and/or photovoltaic (also in the near future we are going to offer low voltage and fire alarm services, so stay tuned)! It is important to her that ELS-T's customers are 100% satisfied because the efforts and hard work we put in is a reflection of that.

After graduating from DePaul, Mindy tried different jobs within different industries, but she couldn’t see herself staying in them long-term pursuing a career. She wanted to get into the electrical industry & ELS-T gave her the opportunity to work in every position. From being the warehouse manager, project manager, bookkeeper, and everything in between. She worked her way up to President then Owner in 2016. Mindy’s true passion is developing relationships with customers long-term, giving them the confidence that ELS-T will be there in years to come.
