John Moetteli

Community

Since 1997, I’ve called Switzerland home—first in Geneva and now in Arbon, where I live with my wife, Novella, and our children. As a history and castle enthusiast, the area is a dream. I’m an IP attorney helping entrepreneurs protect their innovations and brands across the US, EU, Switzerland, and Liechtenstein. With a background in engineering, business, and law, I’ve worked at NASA’s Johnson Space Center, with work featured on the Discovery Channel, and currently teach IP law at ZHAW. A long-time member of AIC Geneva and AICZ, I enjoy being part of this vibrant international community. I speak English, French, and German—and hope to add Italian soon!

Geneviève Cox

Standing Committee member

Geneviève has been living in Zurich for almost 20 years. She is French but she also speaks English, German, Swedish and some Spanish and Italian. Obviously, she loves anything that has to do with languages, but also art and communication in general. Being French, her idea of bliss is to go see a movie,  a play or an exhibition with friends and discuss it for hours in a restaurant or a café.

She has worked as an actress, a chorist, a language teacher and lately as a translator. She would now like to devote herself to her first passions: theatre and opera singing, which she has pursued all this time.

Geneviève loves Americans for their openness and their easy contact. At the AICZ, she has already met a lot of exciting people and taken part in great events. She is thrilled to start getting more involved as a standing Committee member.

Yvonne Nagel

Standing Committee member

Yvonne’s expatriate journey began in her mid-twenties when she left Melbourne, Australia, after studying logic, literature, and linguistics, later transitioning into accounting. This shift led to roles in investment and merchant banking across Melbourne and Frankfurt. What started as a short-term move in the early ’90s became a decades-long European journey through Germany, Luxembourg, and ultimately Switzerland. Navigating patriarchal business structures and cross-cultural dynamics taught her resilience, humor, and the value of expat friendships. Following a personal loss, she launched a remote support business in 2024. Now based in Zurich, she enjoys its quality of life while embracing new adventures ahead.
