Owner
I have known the Owner / Master Electrician for many years. His work is consistently excellent and always done in a timely fashion. No mess / no fuss / no complaints. He is presently replacing my original breaker box which had a fire in it over the weekend. I wouldn't trust my home or my family's safety to anyone else.
