Mindy Nowakowski

President, Mindy Nowakowski leads the company at Eco Lighting Services and Technology, LLC (ELS-T). We make our customers aware of the amount of money they can save and the benefits they will gain by hiring my team of experts to upgrade their lighting and service their electrical needs, including low voltage, small tenant build outs and photovoltaic. It is important to me that our customers are 100% satisfied because the efforts and hard work we put in is a reflection of that.

A lot of our business comes from referrals because we develop long term relationships with our customers. The job is not over once completed, we are there for our customers for the long term. 

I have established ELS-T with many certifications including: WBE with cook county/city of Chicago, WBDC with WBENC, DBE, CMS, SBE, MWRD, CPS and WOSB certification.
