"From the office folks to the electrician who did the work -- friendly and professional. They quoted the lowest price of three estimates and did the work within a couple of weeks. I purchased my generator elsewhere online... and VMA walked me thru the process of hooking it up, running it, and shutting it down. Very helpful."

"I will recommend Champion Electrical Services to anyone interested in hiring competent, reliable and honest electricians. It starts with salesmen Jayron Diaz who submitted the job estimate to upgrade an electric panel to code. There was no surprise costs. Jayron was very professional and honest about the work. On the day of the service, Matt Wood and Sean arrived at the scheduled time as promised. Matt explained what they were going to do, how long it would take, and if I had any questions. Matt estimated the job would take approximately 6 hours. It actually only took 4 hours from start to finish and that included cleanup and minor repairs. I think Champion did an awesome job and I will call upon them for my next project."

"Jason and his team with Cotti-Johnson did an excellent job updating our electrical boxes, installing the washer/dryer hookup, and getting us setup with a generator! Sam, our assigned electrician, even took the time to go through the entire operation of the generator from A-Z. I would definitely recommend them for any electrical work!"
