And now they are five. C&G Partners, the interdisciplinary and superhumanly creative design firm founded by Steff Geissbuhler, Keith Helmetag, Emanuela Frigerio, and Jonathan Alger, has added two partners to its ranks: Maya Kopytman (left) and Amy Siegel (right). The recently announced appointments highlight the New York firm’s expertise in interface design, signage, and print graphics. Kopytman, who joined C&G as an associate partner in 2006, heads the firm’s interactive design practice. She has led many projects, including websites for Riverkeeper, the Samuel H. Kress Foundation, and ARTstor. Siegel, who specializes in signage and environmental graphics, has been with C&G since 1998. She recently completed a stellar sign program for the Hearst Tower as well as sign programs for the new Yankee Stadium and the Bank of America Tower. Siegel is currently working on the 9/11 Memorial Site and Museum at Ground Zero and the Stavros Niarchos Foundation Cultural Center in Athens.
