McGuire Igleski & Associates, Inc. is an interdisciplinary architecture firm founded in 2001 and headquartered at 1330 Sherman Avenue, Evanston, Illinois. The firm specializes in historic preservation, with three core service lines: Preservation Architecture (restoration, rehabilitation, adaptive reuse, reconstruction, material conservation, building relocation, and sensitive integration of modern MEP systems), Architecture (renovation, compatible additions, exterior envelope assessment, sustainable design, accessibility improvements for existing buildings), and Preservation Planning & Urban Conservation (cultural and historic resources surveys, historic structure reports, Section 106/707 consulting, HABS/HAER documentation, design guidelines, tax credit applications, and landmark nominations). Operations are anchored in the Midwest region, predominantly Illinois with active projects in Wisconsin.

The firm serves a diversified public and private sector client base, including higher education institutions (Northwestern University across 50+ campus buildings, University of Chicago, Marquette University, Lake Forest College), K-12 education (Chicago Public Schools), municipal and government agencies (Chicago Transit Authority, Chicago Housing Authority, Chicago Park District, the City of Chicago, City of St. Charles, City of Joliet, McHenry County), real estate developers (Related Midwest, Heartland Housing, Urban Juncture, Metropolitan Pier and Exposition Authority), cultural and nonprofit institutions (Taliesin Preservation, National Public Housing Museum), and religious organizations (Church of Jesus Christ of Latter-day Saints). McGuire Ingleski & Associates is a women-owned business enterprise holding WBE, DBE, and Capital Development Board pre-qualified vendor certifications.

The business model is project-based professional services delivery.

The firm frequently serves as consulting preservation architect to larger prime design teams (Gensler, HED, Walsh Group, NIA Architects, Landon Bone Baker Architects). Pricing is not publicly disclosed. Five principals (Mark Ingleski, Amy Gauen, Sarah Haas, Erica Ruggiero) lead the firm with specialized expertise in preservation architecture, complemented by a preservation specialist (London Hainsworth), totaling seven listed team members.
