As an architect, working with a client is more art than science, and very similar to how Zweig Group works with us, but they do it better. They exercise the power of an open mind, but with the precision of a structural engineer… which turns out to be the key to endless possibilities.

Zweig gave us the confidence that they can provide us with a service that aligns with the goals of our firm rather than just selling us something.  It just made sense to choose them, and then they delivered well beyond what we had expected so we will be working with them again.
