Altenburger – Swiss Business Law Firm since 1978

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.

Mr. Jeong Su Kim, Legal Counsel at LS Cable & System Ltd.

“In representing our company in a high value ICC arbitration case, Clarisse von Wunschheim and her team passionately advocated for our company. I was impressed by their responsiveness, the quality of their services, their result-oriented approach and their commercial acumen.”

Oriol Saludes, COO and Co-Founder Kemiex

“I've been working with Altenburger since 2016. They have supported me both personally and professionally and always went the extra mile. Thierry Thormann's corporate/M&A team and Luzi Cavelti's tax team are very professional, pragmatic, business-minded and experienced. I would highly recommend Altenburger to anyone looking for a law firm in Switzerland.” (April 2021)
