Markey Engineering was founded by Kathryn Markey in 2026 to bring disciplined business leadership together with proven, field-tested engineering expertise under one St. Louis-based firm. Kathryn built the company's foundation — its branding, compliance structure, and operations — while Austin Markey brought nearly a decade of hands-on underground utility and sewer construction experience to the firm's technical work. As a woman-owned engineering firm, Markey Engineering is committed to bringing both operational excellence and deep field expertise to public infrastructure work across the region.
