“During the construction of two Paradise Valley fire stations to be manned by the Phoenix Fire Department, I had close daily contact, in person, by telephone and by e-mail, with TSG Constructors LLC officials. I found them to be diligent, fair and honest. I also found TSG to be, by clear intention, a “team player” with the architect, Town of Paradise Valley, the Phoenix Fire Department, and other agencies. Disputes, even when not resolved to the liking of TSG, were business-like and fact-driven.”
