Levi moved my company from a 1500 sf office to 2400 sf. He gave us a bid that was competitive with two other bids. His team showed up at 7am, and worked straight through until the work was completed. We expected to be done by 3pm, and when it appeared we wouldn't finish in time, Levi brought three more workers to ensure we'd be done in time, and he didn't charge me any more for it!
It's obvious to me that customer service is important to Levi, and I've already referred him to two other clients.
