Full-service Swiss legal and tax advice for US corporations, funds and individuals.
40 years of trusted advice

The US as the leading world economy is, together with Germany, Switzerland's most important trading partner. The land of opportunity not only influences the Swiss economy – it also shapes the Swiss legal profession.

Many of our international clients are from the US. Some of them have entrusted us with their legal affairs ever since our firm has been founded over 40 years ago. And our personal connections to the US are strong: The founder of our law firm, Peter Altenburger, was the co-initiator of the tax chapter of the Swiss-American Chamber of Commerce, and most of our lawyers have lived, studied or worked in the US or even grew up there.

US mentality with a Swiss touch

While our firm is deeply rooted in Switzerland, we live the principles the US stands for: diversity, open to new technologies and an attitude of getting things done. We add our distinct Swiss touch to these great qualities by providing well-founded legal advice for your specific needs. In short - we help US clients realize great opportunities in Switzerland.

Business is always a two-way street. Accordingly, we also assist Swiss-based clients in their outbound US business ventures. To ensure practical and personalized advice, we work in close cooperation with our extended network of law firms and service providers all across the US.
