  • "Just wanted to drop you a line to express my appreciation for your help, responsiveness and work. The facilities you all delivered were perfect. You all worked in a timely and professional manner and it is really greatly appreciated. We will be recommending your company to everyone."

  • "It was a true pleasure to work in a city where people were not only excited about our film, but also willing to help out in any way they could. A-John exemplified this spirit of cooperation and enthusiasm for the task at hand, and were definitely a team of ‘make-it-happen’ people. It became readily apparent to us that great pride is taken in all you do; the result is a high quality of work that exceeds most standards of excellence."

  • “If there was one good thing to come out of Warwick’s water main break, it was the posh portable potty in St. Anthony’s facilities. A plush, state-of-the-art potty with polished steel exterior was on hand Monday for hospital employees and visitors. And it was air-conditioned. Hospital administrator Jeffrey Reilly joked that it was way better than the hospital bathrooms.”

I really appreciate (and so do our guests) the upgraded johns you bring us while still allowing us to keep our costs down.
