Alto-Shaam History

Our History

Our company is built with an entrepreneurial spirit. Conceived in the 1950s, Jerry Maahs was just looking for a way to deliver hot chicken to customers during Wisconsin's frigid winters when he developed the first Alto-Shaam oven. Since then, Alto-Shaam has continually responded to industry needs to ensure that all food service providers have access to high quality cooking equipment. Learn more about where we came from and how we continue to innovate the foodservice industry to better meet our customers' needs.
