Performing For Over 40 Years

Meet the Altenburger Professionals

Since 1978, we have continuously built our authority and reputation as an international business law practice. Growing from a small tax law boutique to a full service commercial law firm has been quite an adventure. We look forward to the years to come!

Client Endorsements and Industry Recognition

Maintaining our clients' continued trust by delivering measurable results is what is most important to us.

Yet, we are of course also pleased when the quality of our service is recognized publicly. Here is some of the recognition we have gratefully received from clients and peers in recent years.

Jimmy Tian, Legal Department at Startimes Group

“My colleagues and I all feel very fortunate for having engaged Dr. Clarisse von Wunschheim and her team as our counsel in our arbitration case. She is really an expert in handling the arbitration process in every phase. She made us feel confident with her patience, professional analysis and well-prepared written submissions. We very much appreciate her dedication in managing this arbitration case for our company.”

Roger Meister, CEO / Partner, 2XIdeas

“We relied on Altenburger's services to structure our shareholders’ agreement, to define our employee participation program from a legal and tax perspective, and also to structure our international expansion in a tax-efficient manner. Not only was the legal and tax input from Thierry Thormann and Luzi Cavelti highly valuable, but we also appreciated the fact that we received substantial best-practices feedback from a busines perspective from them.”
