Our success is attributed to open communication, problem-solving skills, dependability and project leadership. These qualities are foundational to Ostrander Construction and the way we work and have helped us build trust-based relationships with our clients as well as our employees, subcontractors, architects/engineers, and others involved in the construction process.



In 1993, with an entrepreneurial spirit and deep knowledge of commercial construction, Lee Ostrander founded Ostrander Construction. Beginning as a “team of one,” Ostrander built a trust-based commercial construction firm that now employs more than 25 people in the Chicagoland market.

From its inception, Ostrander has focused on delivering high-quality construction projects and building long-term relationships with each client. With steady growth came a diverse and experienced management team who have allowed us to pursue other markets including medical office, industrial, retail, education, wellness, and government facilities.


Our years of amazing work would not have been possible without committed and passionate people. We are fortunate to have many long-term employees on our team.
