After her time in Perugia, she moved to Milan to work at C&B Italia (now
B&B Italia) in communications and public relations, working closely with the company's founder and chairman
Piero Ambrogio Busnelli. She describes her role during this period of her career as "Busnelli’s assistant, public relations office, and interpreter (he spoke no English). We travelled the world. It was incredible." The event is held annually in conjunction with the larger Milan Furniture Fair (iSaloni), an international trade and design event first held in 1961. Griffin is the curator of SaloneSatellite and has an advisory role in the management of the overall design fair. She is considered a mentor who has contributed to the careers of well known designers such as
Matali Crasset, , , , Paul Loebach, ,
Oki Sato, and
Nika Zupanc, and others whose work was first exhibited at SaloneSatellite. The artist and designer
Ini Archibong has said, "I owe a great deal to Marva and Satellite, and I consider myself blessed to have come in contact with such a powerful design gatekeeper."
Paola Antonelli of the Department of Architecture & Design at
Museum of Modern Art (MoMA) once called her the “great godmother of design.” == Awards and honours ==
