What Margaret Sullivan Studio does

Margaret Sullivan Studio is a New York City-based strategy and design consultancy founded in 2014 by Margaret Sullivan, specializing in the transformation of public libraries and civic/cultural institutions for the 21st century. The firm serves municipal and county public library systems across the United States — including New York Public Library, Chicago Public Library, Las Vegas-Clark County Library District, Richland Library, D.C. Public Library, and Fresno County Public Library — with a portfolio of 40+ library system engagements over its 10-year operating history. Its core offering is built on a proprietary methodology called "Library As Studio," co-developed with Patrick Quattlebaum of Harmonic Design, which applies human-centered, equity-driven participatory design and creative placemaking to facility planning and programming. The firm has also extended into adjacent work such as the Bridge Golf Foundation STEM Learning Center in Harlem, indicating modest vertical diversification beyond public libraries.

MSS delivers professional services across six practice areas: Architecture & Interiors, MSS Placemaking, Visioning & Programming, Strategic Planning, Facilities Master Planning, and Community Engagement. Its team of six includes a Principal (Margaret Sullivan), Director of Strategy (Jade Esplin), Strategic Designer, Designer/Urban Strategist, Designer, and Bookkeeper. The firm operates a curated delivery model through a network of 12+ named collaborators spanning architecture (Cannon Design, Bohlin Cywinski Jackson, Arch Nexus), economic development (HR&A Advisors), urban planning (Karp Strategies), and library consulting — enabling multi-disciplinary engagements without proportionate headcount expansion.

The business model is project-based professional services consulting: revenue is generated through strategic planning, facilities master planning, architecture/interior design, organizational development, and community engagement engagements, with pricing varying by scope and library system size and not publicly disclosed. GTM is sales-led and relationship-driven, relying on direct engagement with library directors, city officials, and community leaders, reinforced by thought leadership (NY Times feature, Interior Design Magazine recognition), industry conferences (PLA), and a portfolio of award-winning projects (Library Journal Landmark Library 2019, Library Journal Social Spaces 2024, American Libraries Showcase). The firm is privately held, founder-controlled, bootstrapped (no disclosed funding rounds or institutional investors), and operates from a single NYC headquarters at 307 7th Avenue.
