"My wife and I had extensive interviews with 11 different contractors to build our dream home. One of our requirements was to see their previously built homes first hand. Every one of them needed to make phone calls and appointments to view the homes at a later date. Only Tony Longo and his team said no problem let’s go now. We went to his client homes without appointments and he was greeted at the door like it was his own home. Every owner embraced him as a brother. That convinced us to hire him immediately. After he built our home, I now consider him a best friend and brother, so much so that we engraved his name in stone on our dream home."
