    A: Verified L3W Inc. dba LW Construction Customer, 1 of 163
    "I would say that they're really good at analyzing a problem well enough that even if you've had many different people look at it and everybody scratched their head, he looks at it and he has a hypothesis. He looks at it more, investigates, and then comes up with a meaningful plan. I had several of these kinds of issues and in all these situations he had an actual solution that he was able to implement and solve the problems. He doesn't jump to any conclusions, he solves the problem. Good analysis of the problem and good execution of the solution" - B. B. B. S.
