“During a leadership training session, the facilitator defined leadership as ‘the ability to develop relationships based on trust, respect, and credibility.’ That definition has stayed with me. It’s simple, clear, and applies to everyone in our organization. From seasoned project managers to first-year apprentices, we all can lead by building strong relationships. When we do that, everything else falls into place.” Bob Kaemmerlen

100th Anniversary

Hitting the century mark is a major milestone for any company, so when Kaemmerlen reached 100 years in 2024, it was a time to both reflect and celebrate.

In retrospect, the company’s existence has always mirrored that of the United States. For example, Kaemmerlen jumped on new opportunities when America engaged in World War II; in the post-WWII era, fast food service boomed and Kaemmerlen responded with its commercial foodservice repairs. It also expanded its teleconferencing solutions after COVID-19, due to a high demand. In short, much of Kaemmerlen’s success is based on how it adapted to the changing times.

The other contributing factor to Kaemmerlen’s success and longevity are its employees. Their health, safety, and well-being guide every decision Kaemmerlen makes, from planning and training to daily operations. By fostering a culture of accountability, communication, and continuous improvement, Kaemmerlen strives to ensure that everyone goes home safely at the end of every day.

With its robust history, agility to adapt to the changing times, and commitment to its people, Kaemmerlen is poised for the next 100 years.
