“We can’t say enough about Reggie and his work.”

Reggie is not only an incredible electrician, but he’s also a genuinely great person. He was the main electrical contractor for our large scale commercial buildout, and he handled it all with poise, professionalism and workmanship that was well received by us and the other trades. He went above and beyond to make sure things got done at the right times so as to not hold anyone else up, even when schedules were disrupted from unpredictable circumstances.

Overall, he handled simple electrical work, upgrading from 200A to 400A service, installing and commissioning a 60KW generator, and so much more. Him and his team made sure to fix anything that wasn’t up to par, and were reliable, dependable, and then some.

We can’t say enough about Reggie and his work – highly recommend! We’re glad we found him and you will be too. He’s now our go to for our business, our home, and anyone that asks for an electrician recommendation.

“The communication when I call is second to none.”

Martinez Electric is my go to vendor for all of my electrical needs. As a facilities manager with five buildings to maintain, when I call them I usually have a problem. Besides their fantastic workmanship and knowledge the communication when I call is second to none.
