Blue Isle Granite & Tile | Manassas, Va.

Blue Isle's precision work in installing kitchen counters, a desk and a ledge clearly made Nicholas Schandler a fan.

"Watching co-owner Ike Iskenderoglu work, I was impressed with his attention to detail in making sure everything was done perfectly," he says. "Ike had a lot of good suggestions, but only offered them when we asked for them. Like a good waiter, he was there when you need him and invisible when you don't."
