Mancini•Duffy/TSC

Mancini•Duffy/TSC is a full-service design firm specializing in architecture, planning, interior design, and graphic design services. The firm has been in business since 1920, established as the corporation of Halsey, McCormack & Helmer, architects of such landmark buildings as the Williamsburgh Savings Bank and the Dime Savings Bank in Brooklyn, and the Dollar Savings Bank in the Bronx.  In 1967, Halsey McCormack & Helmer combined forces with Duffy, Inc. (established in 1955) to concentrate on the unique aspects of interior architecture.  In 1986, Duffy, Inc. joined with Ralph Mancini Associates (established in 1981) to form Mancini•Duffy.  In 2001, Mancini•Duffy introduced its strategic planning group, the Center for Workplace Innovation (CWI), which helps clients optimize their investments in their workplaces.  In 2011, Mancini•Duffy acquired certain assets of TSC Design, further diversifying the firm’s retail practice and providing our clients with a deeper and broader set of resources.

Today, the firm is headquartered in New York City, operating as Mancini•Duffy/TSC. For international assignments, we work integrally as IPiD—International Partners in Design—where we further combine local knowledge with global expertise from our primary office in London.  Our global reach also extends to East Asia and Australia through our associations with firms based in Singapore and Sydney. The full reach of our capabilities extends to twenty-eight offices in fourteen countries.

Whether we are undertaking the planning of a relocation, expansion, or consolidation, our clients rely on us to be their trusted advisor.  We are known and valued for our integrity and responsiveness; for the attentiveness with which we listen, the clarity with which we communicate, and for our ability to deliver results that meet our clients’ needs and our own high standards.  Those clients—many of long standing, for whom we have undertaken numerous assignments—include corporate, commercial, governmental, and academic institutions; our experience with interiors encompasses projects for financial service firms, publishing houses, law firms, advertising agencies, retailers, and hospitality companies.
