A comprehensive practice, our work traverses the world of accessories, focusing on the design and development of footwear and handbags, while extending broadly for certain houses, including fine jewelry, fragrance and furniture.
Our studio on Manhattan’s Broad Street, in the emerging fashion district anchored by Conde Nast, is a full-service agency with a proven track record in the formation of new businesses, the category extension of existing brands, and the reinvigoration of venerable companies. With a history spanning luxury and technology, we have been instrumental in the success of our clients for over a decade, a roster including Calvin Klein Collection, Derek Lam, Marchesa, Hunter Boot, Monique Lhuillier, Judith Leiber, Ghurka, Cole Haan and many others.
From capsule collections to complete rebranding, Design Quadrant's broad scope and comprehensive global network are a turn-key resource for the industry. As "ghost" designers, we can successfully operate in tandem with your current design team, or work separately to develop new businesses, deliver advanced R&D projects, or restructure your business for a changing landscape.
FRANK ZAMBRELLI was headed for medical school when an unexpected trip to the European shows radically altered his plans. Heading instead to the Fashion Institute of Technology, he graduated with a dream job at Chanel, alternating his time between Paris and New York. John Varvatos, then at Cole Haan, gave him his next big break, the opportunity to further develop his craft in European factories. His tenure led him to Coach and the successful launch of the venerable firm’s foray into new businesses. In 2003, with support from the global fashion community and press, Design Quadrant was born, shaping collections and brands across the luxury sector. Beyond the studio, Frank is the current Chairman of the Accessories Council, serves on the Alumni Board of Directors of the FIT, and is the Senior Advisor to Glasgow Caledonian University's Fair Fashion Center.
Prior to joining Design Quadrant, SARA DALY ROTER worked with Grey Global, where she supervised key media outlets for major brands within Diageo (KetelOne, Johnnie Walker, Smirnoff, Baileys, Crown Royal). She honed her marketing and design talents at Parsons School of Design in New York. Becoming a partner in 2006, Sara now focuses her efforts on Design Direction and Product Development. Steering the design team, Sara plays an instrumental role with each brand and collection, directing color, trend and materials with each of our global partners. She spends considerable time in Italy and elsewhere sourcing macro trends and inspiration for the studio and it's clients.
SILVANO BANFI was born into a shoemaking family in Milan, and by an early age was working with some of the finest houses in Europe. By the time he was 18, he was designing and producing for the likes of Gucci, Bally, Lario and Gianni Versace. After leaving the prestigious ARS Sutoria Institute in 1994, he arrived in the U.S., honing his talent with Calvin Klein, Banana Republic and Coach. At Coach he met Frank Zambrelli, where they collectively launched the brand’s very successful extension into footwear. In 2003, they joined forces once again to pursue a more personal vision of how beautiful accessories should be made.
