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.

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.”

Tobias Antius, CEO at Novotek AB

“Altenburger helped us with an acquisition of a Swiss company. We found them via reference by our accountant and they provided great support and were very quick in responding to any request or change. Since the acquisition was rather limited, the ability to scale and adapt the agreement structure as well as managing the communication with the counterpart were key to the success of the deal. Thierry and his team delivered and met all our expectations. I believe their way of working helped close the deal faster and that is key to me.”
