"We hired Mark in install our gooseneck lights for our sign at our beer and wine shop. Mark went above and beyond everyone I've hired to do work at all of our businesses.
I'll explain how... Our landlord wonder detailed work description(with diagrams), copy of liability of insurance forms, permits(which Mark pulled right way)... This is before we even got the approval from our landlord. Then after we got the approval Mark had to custom make the arms for the goosenecks because the landlord would not let us install the lights on the brick wall of the building.
This is where most electricians would have quit( it had happened with other project at our shop) and hell I would have if I was Mark but he made them and installed them in this cold freezing weather. I would highly recommend Mark he is honest, smart and very reasonable!"
