In 1921, Angelo Perciabosco began a humble yet earnest electrical business in his West Side neighborhood in Chicago. Like other true craftsmen of the day, he took great pride in his work and his reputation began to spread. This strong work ethic was passed down through the family.

In 1979, Carmen Sergi and his son Dominic (great-nephew of Angelo Perciabosco) took over the business and helped integrate modern technologies into the growing enterprise.Today, nine decades of hard work have forged a legacy of workmanship, service and pride that lives on in a thriving electrical company that numbers more than 400 employees.

I wanted to take a moment to thank Rex Electric for the excellent job you did on the CDW at 120 S. Riverside Plaza. I especially want to recognize the great job done by your project manager, Will Sutila, and your foreman, Dan Mazurek. Will was very responsive to every issue and detail of the project.

Thank you again for helping out. John McNulty was out here this morning and made quick and easy work of what basically would have been my worst nightmare. We are now not only operational again at home but actually even better off than we were before that stupid storm hit. And for what it's worth, John was unbelievable. A really nice and trustworthy guy. Worthy of the Rex logo for sure.

Thank you very much for your help. Ron dropped by to take a peek at our digital versus analog port quandry and was so incredibly helpful and efficient. In and out.problem solved! He's incredibly knowledgeable and communicates by talking with me, not over my head like most (technical vocab). He's a great problem-solver!

Sometimes it seems people only comment on the bad that happens. I wanted to write you to let you know what an excellent job your company did on our recent changes. We always get compliments on how nicely the wiring is done and the professional job you did on the building in general.
