Our Story

Founded in 1983, McGrath & Associates began with a simple goal – deliver high-quality work while building lasting relationships. A stakeholder partnership helped establish the company’s foundation, but in the early 1990s, McGrath & Associates became 100% employee-owned, ensuring that our team members have a direct stake in not only the company’s success but the success of our clients as well.

Since that time, McGrath & Associates has remained focused on serving organizations through open communication and integrity, establishing a reputation for quality, safety, and reliability across some of the most sensitive and complex environments in our region. From laboratories and operating rooms to industrial facilities and substations, McGrath & Associates delivers consistent excellence that has earned us the trust of long-standing clients like BJC Healthcare, Thermo Fisher Scientific, Mallinckrodt, and Ameren, who have continued to partner with our company for decades.

Who We Are Today

Headquartered in St. Louis, Missouri, McGrath & Associates is an employee-owned general contracting and construction management firm that serves clients throughout the Midwest. We specialize in energy, industrial, institutional, healthcare, pharmaceutical, and commercial markets and continue to be guided by the same principles that have defined us since the beginning: trust, transparency, and an uncompromising commitment to top-quality work and relationships. With more than 80% of annual projects coming from repeat clients, the success of our company is built on a proactive, zero-incident approach to safety, exceptional communication, and an unmatched expertise.

McGrath & Associates offers a comprehensive range of services that blend our extensive in-house expertise with trusted partnerships. Our ability to self-perform key trades – including carpentry, concrete work, millwrighting, and steel fabrication – allows us to have superior control over schedule, quality, and costs. To complement those capabilities, we maintain a select network of specialized subcontractors, vendors, and suppliers who share our commitment to safety, performance, and precision. In 2017, the addition of an in-house architectural design team further enhanced our proficiency, enabling us to provide our clients with high-quality designs, seamless communication, and efficient project delivery from concept to completion.
