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. HISTORY 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.
