A history of hospitality.

In 1986, the owner of the Comestible shop “Zur Münz” in Zug, Peter Gamma, decided to open his sense of deliciousness, his unerring style and his passion as a host to a larger audience. In 2018, Peter Gamma ensured the continuity of his business and passed on his life’s work to the next generation.

Anke Krause, long-time employee and CEO of the group since 2013, takes over the majority of votes of the GAMMA Group together with Thomas Widmer, Managing Director of HAUTE and responsible for the Zunfthaus zur Saffran. In 2021, the shareholder circle of GAMMACATERING was expanded and rejuvenated by two long-time employees Lukas Dietziker Managing Director GAMMACATERING and Niculin Peter.

Today, with around 25 employees and over 250 freelancers, GAMMACATERING is one of the leading Swiss companies in the catering sector, and its festive arrangements are legendary.

Teamwork full of enthusiasm.

Our well-rehearsed teams set the perfect scene for hosts and guests, wherever they are. Meticulous preparation and absolute professionalism are the hallmarks of our work. All our staff are regularly trained to ensure outstanding service and sincere hospitality. Depending on the assignment, we are assisted by selected Partners.
