KELLER Pressure turned 50 this year - definitely a reason to celebrate!

On 27 September 2024, employees, alumni, partners, friends and the Keller family celebrated this significant event at an anniversary party with the motto «Above the Clouds».

The owners, Tobias and Mike Keller personally welcomed around 700 guests on the blue carpet in Winterthur's Eulachhalle. The invited guests have all shaped our company in various ways and accompanied it on its way to a successful future.

Special drinks, show acts and a sky adorned with seagulls symbolically lifted the party above the clouds. The participants looked back on 50 years of success, savoured the moment and together look forward to the promising future of KELLER Pressure.
