SIMION NICK STIRBU
PRINCIPAL

Simion Nick Stirbu, President and CEO, founded SD Electric in 1995. In the winter of 2017, Simion envisioned a new direction for the company, entrusting his twin sons, David and Ionathan, with the roles of property managers and rebranding the business as SDI Electric Group.

Before establishing his own business, Simion worked as an electrical technician for M3 Electric. He is a graduate of Moody Bible Institute and, originally from Romania, developed a strong work ethic early in life. At 22, he moved to the Chicagoland area, where he began his career as an electrical engineer. As a long-time resident of Chicago, Simion takes great pride in both his city and its people.

When he is not working, Simion participates in outreach efforts through SDI Electric, where he and his team are actively involved in feeding the homeless, contributing to the community's well-being.
