The Guckenheimer Story

A simple idea to use real food and generosity of spirit to empower engagement and community transformation in the workplace. 

Our history

It all started with a sandwich

Stewart and Jeanie Ritchie incorporated Guckenheimer in 1967 with a simple idea – to use real food and generosity of spirit to empower engagement and community transformation in the workplace. Over the last 51+ years, the company has grown from a single location to having over 4,000 employees in the United States.

In 2017, ISS acquired Guckenheimer as part of their brand portfolio. ISS is a global facility services leader based in Copenhagen, Denmark.

ISS was founded in Copenhagen in 1901 and has grown to become one of the world’s leading facility services companies. ISS aims to enhance lives and make the world work better through their tailored solutions to meet the client needs, manage risk, and engaged a team of more than 400,000 staff members to help connect people and places to make the world work better.

Guckenheimer is central to the ISS self-delivery model, driving greater value and efficiency for our clients, and improving employee engagement and the workplace experience.



Our Commitment

The ISS and Guckenheimer commitment is to build upon the brand quality already realized, further support the continuation of marketplace differentiation, and provide a food-service self-delivery option for high-quality service levels. A major part of the ISS service strategy is to enhance the workplace experience for clients focused on attracting and retaining top-tier talent worldwide.
