He is experienced in a broad range of national and international transactions, both sell- and buy-side (including corporate auction processes) as well as the assistance of clients in their ongoing corporate and commercial activities.

Stefan Brunnschweiler has engaged in competition law, including merger control filings for more than 10 years.

"I understand that my role as a lawyer is to facilitate transactions rather than make them overcomplicated while always keeping an eye on the particularities of the legal environment."

"I have deep respect for my clients' time constraints. I try to point out the vital issues to the client while dealing with the other legal matters independently."

"Outdoor sports with my friends and time with my family freshens up my mind and is a source of new ideas."
