Was introduced to John by an old friend. After having four electricians look at the 100 amp box I was having trouble with at my home, I received quotes of around $3000 to up the box to 200 amps. John took less than five minutes to look at the box and informed me that I had a 300 amp box, and that my troubles stemmed from a bad neutral which the utility company would be required to fix at no charge. That strongly suggests that the other four electricians, which I had picked up through lists, were either incompetent or unethical. Go with John and his crew; you can rely on them.
