What Our Clients Say

“As any historic renovation project does, this one did encounter challenges… Your firm got to the heart of the matters quickly and expedited solutions, but not without ensuring that the options and selected path were well thought out. Your approach was a refreshing contrast to that I have encountered with other firms.”

—Dr. John A. Latschar, retired Superintendent, Gettysburg National Military Park
