Founder & CEO

Tony Iannessa

Born in Chicago, Tony Iannessa is driven by the work ethic he inherited from his family, who immigrated from Italy in the early 1950s. Having built a foundation working in the trades, Tony’s roots in construction trace back to his youth, when he spent summers as a concrete laborer and interning with an electrical contractor.

After graduating from Indiana University, he gained over a decade of experience in Chicago’s construction industry, which he leveraged to form BIG in 2016. As founder and CEO of BIG, Tony leads the firm’s strategic direction and is responsible for the organization’s sustainable growth.

Tony is an active member of Vistage and Chicago’s Economic Club. He serves as a board member of Susan G. Komen and is an Imerman Angels mentor for other caretakers of spouses fighting breast cancer. He is active in the American Cancer Society Making Strides and Think Pink campaigns and on the Sports and Pastimes committee of Riverside Golf Club. As a founding member of an FMI Peer Group he helps interior construction firms across the country expand their businesses sustainably and profitably. Tony has been featured in Crain’s Chicago Business numerous times and has served in various board positions with Leukemia Lymphoma Society, National Italian American Sports Hall of Fame, Greater Chicago Food Depository and City of Hope.

When he isn’t working, Tony lives in Chicago’s Ukrainian Village neighborhood with his wife and daughter. He enjoys golf, cooking/dining, working out, and relaxing in Harbor Country, Michigan with his family.

It was there that he had the opportunity to work with Tony, now BIG’s CEO, on an interior buildout project. Taking quickly to the team’s energy and the autonomy, Isaac presented a bid in his first week and permanently joined the group shortly after.
