ThomasevenT was founded in 2016 by Thomas Rohrbasser, a graduate of the Ecole hôtelière in Geneva.

Before opening his company, Thomas gained experience in management, running private events for an important bank in Geneva, for several years.

He continues to meet new challenges every day while expanding his professional scope. His philosophy is to foster close relationships with his clients, through a framework of Trust, Communication and Collaboration. 

The core of our business is built on Trust, Consistency and Communication. These keywords build successful long-term relationships.


My greatest pleasure is to see our customers, partners and teams satisfied after each event.

I am delighted to welcome you and hope you enjoy discovering the world of Thomasevent.
