Originally established in 1919, DHA selectively draws on its experience of over 90 years to provide professional design and engineering services which meet each client's specific needs. Our firm's reputation is built on our successes in the markets we serve, with both new construction and renovation projects. What sets Diekema Hamann apart is our unique combination of passion and experience; we take pride in offering comprehensive design and engineering services focused on developing the right solutions for our clients' unique challenges.


Diverse leadership with common objectives. The eight partners of Diekema Hamann bring unique perspectives to its management and culture. An avid volleyball player. A voracious reader. A couple of foodies. A Michigan sports fanatic. It's important to the culture of Diekema Hamann that each partner brings personality to the firm on a daily basis. Our firm is energetic, detailed, competitive, and knowledgeable. They are advocates for our clients and accountable to each other. The partners of Diekema Hamann are proud to lead such an exciting company!
