I've worked with Dave on a series of projects - from a garden fence to a complete home remodel - and found him to be a very skilled designer, able to come up with creative solutions to difficult space and cost constraints. He's easy to work with, doesn't cop a lot of architect attitude, and tells you what he thinks.
If there's one area of concern with Dave, it's that he doesn't always nail down the business details the way he should - items like matching estimates to bills, etc. can get lost in the shuffle. Keep an eye on that and you're sure to be happy with your results.
