Roman Heiz and his team have an above-average ability to grasp things quickly and acts very professionally. They were very personable, competent and committed right from the start. Highly recommended!

Roman Heiz and Nadine Zanetti understood what we wanted to achieve and helped us get there. They explained the legal points extremely well and we worked as one team. Excellent!

Legal 500

I truly believe that the people at Wenger Vieli with whom to work I have been so fortunate, are each and every one unusual in their standards, thinking, competence, professionalism, ethical and moral attitude. I valued that they took great care in explaining everything to me. Qualities I have valued- besides of course the most outstanding legal expertise-: kindness, intelligence, commitment, charisma, the capacity to listen, patience to explain, and everyone I dealt with had a great sense of humour! I would like to mention Roman Heiz and Nadine Zanetti.
