Since 1900, O’Shea Builders has been a trusted name for commercial construction services in Central Illinois.

John O'Shea started the business as a one-man, home‐based carpenter shop in Springfield. Today, O'Shea Builders has grown into the leading commercial construction-services company in Central Illinois, earning the "Top 100 Contractor in the Midwest" designation for the last ten years.  

While our ‘family’ has grown over the years, we remain true to our roots, delivering construction the O’Shea Way. Our mission – to create Exceptional Construction Experiences – represents the serious commitment we make to our clients, employees, design partners, and trade partners on every project. After all, when we work together as a cohesive team, we are equipped to tackle complex problems, adapt to change, and ultimately achieve remarkable outcomes for our clients.

A Tribute to David “Bud” O’Shea, 1934-2022

David “Bud” O’Shea was truly “born to build.” He inspired the O’Shea Team every day with his strong and honest work ethic, character, and love for construction. He was the link between our past and present, having worked with his grandfather John, his father Harold, and his son Mike, who leads the business today. Bud’s legacy lives on in through our company values, which reflect Bud’s unique approach to construction and business: Competence, Commitment, Consistency, Compassion, and Courage.
