Luis and his company did a fabulous job in our kitchen.They were incredibly professional and produced the greatest product possible. They did layout with all options so we could have the best overall product. On a purchase like this you get what you pay for and these guys are hands down true craftsman and experts in their industry. I would like emphasize referells and that is why I am doing this because these guys deserve that referell. They do custom work unlike some of the competitors in the area so don't bargain shop because there are shops in the area that have no business doing custom work
