50 Years of Engineering Excellence: Celebrate with Us!

We're celebrating 50 years of business, and we want you to join in our celebration! We'll be releasing exciting content every month leading up to February 2024, when we have our big celebratory event.

Tour our Awards & Honors projects and meet some of the people who have contributed to our journey and along the way learn some interesting “Did You Know”? facts. We’ll end our celebration with a message from our President as he relates his vision for the future. Stay tuned as we commemorate our history and continue shaping the future together. Thank you for being a part of the DHA Family!

Mamo Assefa, P.E.
President
We invite you to return on the following months:
