40 years. Let that sink in.

Today we’re celebrating David Simpson, whose four decades with Diamond have left a lasting mark on our company and our people.

His leadership goes beyond business. It’s about relationships, trust, and showing up every day with consistency and purpose.

David, thank you for the example you set and the culture you’ve helped build.

We’re proud to celebrate this milestone with you.
