We've had Calvin here twice to help fix problems in the last two years. Each time he's worked hard and fast to solve and fix problems with this old and complex (crazy) well system we inherited. He's warm and friendly, and really knows his stuff. We trust him to be fair and honest with a good sense of humor that you need when dealing with stuff that got rigged by others over the years.
I can't say enough good things about Calvin because he really cares and is willing to go out of his way to make things right. He's the go to guy.
