Our History

Founded in 1979 by William T. Connelly Sr., Connelly Electric exists to provide a valuable partner to general contractors and developers requiring electrical services for commercial building projects.

William began operations from the basement of his home with his two oldest sons, William Jr. and Joseph. In 1986, they welcomed Kevin into the developing company. The company continued to grow, and in 1989, William T. Connelly Sr. passed away and handed the company down to his sons.

Carrying on the legacy left by their father, the Connelly brothers continued adding projects and services to their experience. In 1990, they welcomed the fourth brother, Brian, into the business. As the scope of each project continued to grow, so did Connelly Electric’s revenues and size. In 1998, Connelly Electric moved into a new office building to meet the needs of its growing customer base and workforce.

As a testament to the dedication, experience and dependability of the company, Connelly Electric has grown to become one of the most well-known and well-respected names in the industry. Connelly Electric has added an office in downtown Chicago to facilitate their continual industry presence and service in the Chicagoland area.

Looking to the future, Connelly Electric is committed to continue growing with our clients; providing the electrical designs, solutions and infrastructures to help them develop and succeed.
