What Antinozzi Associates does

Antinozzi Associates is a Connecticut-based architecture and interior design firm founded in 1956 in Bridgeport, operating as a privately held professional corporation (Antinozzi Associates, PC). The firm delivers design leadership across four primary verticals: K-12 and higher education, institutional and government facilities, commercial development, and multi-family residential. Its core services include architecture, interior design, master planning, programming, space planning, feasibility studies, project management, consultant coordination, site analysis, pre-referendum services, and high-performance building/LEED consultation. Underlying technology centers on Autodesk Revit-based Building Information Modeling (BIM) workflows, supplemented by LEED and WELL building-standard certification capabilities; the firm does not disclose use of AI/ML or proprietary technology platforms.

The firm operates a professional services revenue model, earning fees on a project-by-project basis through competitive bidding, RFP responses for public-sector work, private developer engagements, and long-term on-call contracts. On-call relationships with the Stratford Housing Authority (since 1981), Town of Trumbull (since 2010), University of Bridgeport (since 2002), University of Connecticut (since 2014), Greenwich Public Schools (since 2015), and West Haven Housing Authority provide recurring baseline revenue, while large competitive projects (Platt HS at $112M, Stratford HS at $126M, Cranbury ES at $45M, Washington ES at $40M, CREC Medical Academy at $64.5M) drive cyclical peaks. Principal-led teams manage engagements from inception through construction administration, with marketing conducted principally through the firm website, LinkedIn, Instagram, Facebook, and earned media in regional outlets such as High Profile Monthly.

The firm is led by three principals — F. Michael Ayles (Principal of Business Development, AIA Fellow), Paul A. Lisi (Principal and Director of the Architectural Studio, Licensed Building Official), and Michael LoSasso (Principal, DAS School Construction Grants specialist) — following an April 2021 succession from founder Paul Antinozzi, now Principal Emeritus. Customer concentration is heavily skewed toward Connecticut public-sector clients, particularly K-12 school districts, municipal governments, and housing authorities, with operations predominantly in Connecticut and limited exposure to Rhode Island.
