"Of all my experiences dealing with a utility company, this has gotta be the best I've every had. I would whole-heartedly recommend anyone checking out Gault for your energy needs. The woman I spoke to who first helped was informative, personable and took the time to make sure I understood every thing. I was so impressed I signed up on the spot..."
