Nicholas Siewerth is a Project Executive at The Missner Group with more than 20 years of experience in construction project management. In his role, he oversees The Missner Group’s construction team across all active projects, with a consistent focus on safety and operational excellence.
His background spans large-scale, complex projects across the full project lifecycle — from preconstruction planning through closeout — with a focus on keeping schedules and budgets intact.
Nicholas has spent his career working through the real challenges of construction: coordinating multi-trade teams, managing risk, and solving problems before they compound. That experience informs how he approaches every project and every conversation.
He is currently overseeing Oxxford Lofts at 1220 W. Van Buren St., a historic industrial conversion to multifamily in Chicago — a project that reflects the kind of complex work he has built his career on.
