Our verification notes

The credential strings here are read directly off signed engineering reports, which is the strongest verification form in this whole directory. One caveat: the letterhead office signing those reports is GEI's Milwaukee, Wisconsin office, while the Michigan entity is a separate professional corporation. Confirm which office would carry an assignment.
