A record-setting project called for a carefully engineered solution.

At ADM’s soybean processing facility in Des Moines, Ahern designed and installed the largest fire pump room in our company’s history while helping the facility remain operational throughout construction. From complex hydraulic demands and custom components to a tightly coordinated shutdown and innovative system testing, the project showcased the planning, expertise, and teamwork required to deliver a fire protection system built for massive demand.

For 56 years, Ahern’s Recognition Dinner has celebrated the people who have helped shape our company through their experience, dedication, and commitment.

This year, we recognized 136 employees celebrating 10 or more years with Ahern, including 79 employees reaching their 10-year milestone for the first time.

What began in 1969 with just 20 employees being recognized has grown into one of Ahern’s longest-standing traditions, bringing employees and their guests together to celebrate the relationships, accomplishments, and careers built along the way.

Congratulations to all of this year’s honorees, and thank you for everything you contribute to Ahern!

Once part of Ahern, always part of the Ahern story.

This year, we welcomed 48 retirees back to Fond du Lac for our annual Retiree Luncheon, an opportunity to reconnect, catch up, and recognize the lasting impact they’ve had on our company.

The tradition dates back decades, with retirees originally joining our Recognition Dinner before Ahern created a separate luncheon in 2009. Today, both events continue to celebrate the people who have helped shape Ahern across generations.

We’re grateful for the dedication, knowledge, and contributions of our retirees and the legacy they continue to leave behind.
