Our Team


With a staff team of 100 engineering design and service professionals and support staff, plus licensing in 29 states, Ring & DuChateau is large enough to tackle major projects, yet small enough to cultivate personal relationships with clients.  We are all committed to design excellence through a collaborative process with our clients, and within our own teams to achieve integrated design delivery.
