In 1986 Peter Gamma, owner of the “Zur Münz” food store in Zug, decided to bring his taste for the exquisite, his unmistakable style and his passion for hospitality to a wider public. Today, GAMMACATERING is one of the leading Swiss companies in its field, with around 15 employees and more than 250 freelance staff. Its party arrangements enjoy a legendary reputation.
Sustainability with distinction.
The examination was tough, the results outstanding: GAMMACATERING is the first catering company in Switzerland awarded the distinguished certification as a “Sustainable Company powered by the FAMAB”.
We are pleased, and immensely proud, as this title confirms our sustainable development and actions in all relevant areas of our industry.
We are also committed to support smaller food producers and certified products from Fairtrade Max Havelaar.
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.
