What Mancini Duffy does
Mancini is a New York-headquartered architecture, interior design, and planning firm with a 110+ year operating history, operating under the legal entity Halsey, MCormack & Helmer, Inc. The firm is co-owned by CEO William Mandara Jr. and President Christian Giordano, employs approximately 140 professionals across seven US offices (New York City; Red Bank and Millburn, NJ; Seattle, WA; Scottsdale, AZ; West Palm Beach and Tampa, FL), and reports annual revenue of approximately $31 million as of January 2025. It serves enterprise and mid-market clients across at least 18 verticals including financial services, healthcare, hospitality, retail, real estate development, aviation, education, and government, with anchor relationships such as HSBC (since 1986), Starbucks, Louis Vuitton, Tiffany & Co., Spotify, Morgan Stanley, American Airlines, Lufthansa, NYU Langone, and NYC EDC.
The firm positions itself as a technology-first design practice, anchored by a proprietary Design Lab R&D division that has produced several in-house technology platforms: The Toolbelt (a patented VR/AR/MR visualization platform invented by President Giordano), Mancini:Link (a mobile VR and database application enabling remote client design reviews), generative AI workflows using Adobe Photoshop's Generative Fill and MidJourney for conceptual design (used in Lilly Pulitzer Reimagined), AR-assisted floor plan verification for construction accuracy, the MicroFactory on-site 3D printing service, and AI-enabled drone mapping and photogrammetry. Documented ROI from these tools includes 40% installation cost savings from 3D-printed elements, $10,000 saved per project on in-person presentation costs via Mancini:Link, 144x faster site surveying via drones, and $25,000 saved on post-production marketing content via game engine visualization.
Mancini's business model is project-based professional services delivered through enterprise field sales, with no public pricing or standardized rate cards. Services are quoted per project based on scope and complexity, and the firm manages long-tenured enterprise relationships that span decades and multiple locations (e.g., HSBC 400,000 sf across 8 metro locations, Lennar across multiple Florida developments, Boqueria multi-location rollout). Distribution is conducted through seven regional offices, direct principal-led engagement, and a thought leadership platform including The Anti-Architect Podcast (hosted by Giordano), industry press, and dedicated sub-brands MDLX (interior finishing) and the acquired Design Styles Architecture subsidiary.
