Company Overview

For additional details, please check our website. In 1962, Clarence Thoma launched Thoma Electric. His sons, William (Bill) and Edward (Ed), grew up immersed in the business. William obtained a degree in Electrical Engineering from Cal Poly State University in San Luis Obispo. Edward received his degree in Industrial Technology from Cal Poly. The brothers acquired the company from their parents in 1989. Since 1981, we have included Electrical Engineering in our services, witnessing consistent growth. Our workforce typically ranges from 60 to 70 employees, peaking at 150 during a five-story hospital project in Santa Maria for Marian Hospital in 2011. Thoma Electric features divisions dedicated to Electrical Engineering, Major Electrical Construction, Small Electrical Construction, and Electrical Services. “Every project matters, no matter the scale”. We handle projects from start to finish, including design and construction. Our expertise extends to Data/Comm work, copper and fiber installations, solar energy systems, and emergency power solutions. In 1983, I graduated with a BS in Industrial Technology from Cal Poly San Luis Obispo. Between 1984 and 1986, I worked as a Manufacturing Engineer at National Semiconductor, specializing in wafer fabrication. In late 1986, I came back to SLO to work at Thoma Electric as an Estimator and Project Manager. My role has evolved to include Company Safety Director and Manager of the Service Plus division, which handles small to medium electrical projects. Our team resolves electrical problems and manages small time and material jobs for residential and commercial clients. We provide emergency electrical services after hours for urgent needs.

Outstanding service! I had a problem with my electrical box at home, called these guys and the next morning they are at my door fixing my problem. I highly recommend them based on my experience and high touch service. Thanks-

From inquiry to completion, the team at Thoma Electric is outstanding. Thoma has a bad misconception in the community by those that think of them only doing large commercial projects when in reality they truly excel in the smaller jobs. We had originally worked with Thoma to put in some electrical outlets and wire two outside lights a few years ago. Having had a great experience we called again when a couple of plugs in our kitchen weren't working and I got a spark when removing an electrical cord. Making a convenient appointment was seamless and the electrician dispatched couldn't have been more helpful or competent. He explained why the outlets weren't working, identified another issue that he promptly fixed and then recommended that we purchase a new toaster oven, explaining that while we couldn't see the problem, it had a defective electrical cord that could potentially lead to problems down the road. The good news is -- I never liked that toaster oven and I'm happy to purchase another! Whether for new commercial developments, or fixing an electrical outlet in your kitchen, Thoma Electric gets my vote for being the best.

David was incredibly knowledgable, efficient, and swift in diagnosing and solving my electrical problem (hidden breaker). Would definitely recommend.

What a great company!
I needed to install Nema 14-50 for my new Tesla, a few other companies, gave me an estimate over $2000 and made it seems like so complicated due to location of the panel... Thoma Electric made it really simple and stress less, an electrician came to my house at 8:00 am finished the job in couple hours! It was just amazing to watch him working, climbing through the attic bringing thick wire to the garage. So professional, talented and on top of that I asked to fix my indoor outlets and he gladly did and no extra charge! The original estimate was $1300 but today I got the bill from Thoma Electric and it's only $600!!!
Such a honest and wonderful people!
Two thumbs up Thoma Electric!!! I also spoke to Tesla representative and they are definitely going to refer Thoma Electric to other Tesla customers in our community. My #1 electrical company! Thank you so much Thoma Electric!!!! Will be back

We have built a house, done lots of remodels and recently had need of an electrician for something no one could figure out. We were very impressed by the professionalism, thoroughness, patience to find the problem and explain to us what was needed. Loren was great!

For the past two and a half years Thoma Electric has competed both day to day maintenance and complex in-depth remodel/upgrade electrical projects for our office building complex. Professional service, quality work, timely/responsive, all at a fair price are hallmarks of Thoma Electric.

Fast. Easy. Perfect job installing an outlet. Very professional! I called in and John came out the next day with a bid. Even during holidays I was quickly scheduled and electrician was careful to wipe his feet every time he came in. This is the second time they've helped us out --- last time it was a tricky fan installation. Pleased? Indeed. Thanks so much!

I've worked with many electricians and this company is prompt, efficient, committed to doing the job right at a fair price. They are very responsive and will return your call/inquiry immediately. They are available anytime and were very helpful with a home inspection. The electrician was able to diagnose the problem immediately and offer several reasonable solutions. I plan on hiring them to make these repairs after hearing from others their great work. I also really appreciated John's initiative as he found a few additional issues during the inspection that the inspector didn't catch! And one of them he corrected because he cared about doing his job right. So happy to have found a good electrician in the area!

Our spray booth went down which put us at a dead stop for production which leads to all kinds of problems needless to say.
Called Thoma electric as we always do for out electrical needs and they sent Loren over within the hour and he determined problem, told us what was needed, I ordered it and once I recv'd the parts, he came back within a hour of notice and got us back making money.
To all at Thoma, You Guys Are Awesome!

Had an exterior pump outlet issue and, while alternative companies were swamped with work until the next week, Thoma has a service technician out the same day. David was very knowledgeable and friendly, and clearly outlined the fix and what it entailed. He was patient with a variety of service questions and was willing to work with additional requests. Next call for an electrical issue requiring a professional will be to Thoma Electric.
