Company Overview

Visit our site for further information. Thoma Electric was established by Clarence Thoma in 1962. The business environment shaped Bill and Ed, Clarence's sons. William obtained a degree in Electrical Engineering from Cal Poly State University in San Luis Obispo. Ed completed his BS in Industrial Technology at Cal Poly. In 1989, Bill and Ed took over the business from their parents. We added Electrical Engineering to our offerings in 1981, and it has grown steadily. We usually employ between 60 and 70 staff, reaching a high of 150 during a five-story hospital project for Marian Hospital in Santa Maria in 2011. Thoma Electric features divisions dedicated to Electrical Engineering, Major Electrical Construction, Small Electrical Construction, and Electrical Services. “Important projects come in various sizes”. Thoma Electric is equipped to oversee projects from cradle to grave, from design through construction. We also specialize in Data/Comm work, including copper and fiber installations, solar systems, and emergency standby power solutions. In 1983, I graduated with a BS in Industrial Technology from Cal Poly San Luis Obispo. I was employed at National Semiconductor from 1984 to 1986, serving as a Manufacturing Engineer in wafer fabrication. I returned to San Luis Obispo at the end of 1986 to join Thoma Electric as an Estimator and Project Manager. I now serve as the Company Safety Director and Manager of the Service Plus division, overseeing 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.

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.

Thoma Electric did a great job on a commercial project for me many years ago, so when I needed electrical work done on my home they were the first - and only - company I called. John, who handles the service department, came out to give me an estimate. He was prompt, and professional. The estimate was more than fair. He assigned Dave and Kevin to do the actual wiring. Both were prompt, courteous, professional, and took great care to clean up as the work progressed (I have 2 small dogs who will try to eat anything). They installed all new plugs and switches, 3 new 15 amp circuits, and replaced all ceiling and wall fixtures and ceiling fans. They more than lived up to my expectations; I will continue recommending them to anyone needing electrical work. And Ed, you did a great job ""putting the lights in for me."" (I love your commercials!)

I'm impressed! The fact that just part of the lights in our home were not working was mystery enough...then, as I turned off the water on the porch, I leaned against an electrical box (no, not standing in water nor wet hands...) and received a big shock that scared the heck out of me. We also had a couple of other mysteries. Your guys were awesome. Extremely polite and organized and the last technician, Loren, explained things so well that even an old gardener like me actually thought I was understanding it all. In the end...all mysteries solved! The rather unsafe situation on the porch fixed and safe...my questions all answered and Thoma Electric will be the first call I make for anything in the future. I'm pretty nitpicky, so for me to feel this kind of peace is a good thing. By the way, they crawled around in dark, creepy, hot spaces you couldn't pay me to go into. Many thanks!

The economy must be getting a lot better. After calling three local independent electricians in my area with either no returned call or a very very delayed returned call, I decided to call Thoma Electric. I needed some home electrical fixes done, which included replacing switches and light fixtures.

I was very pleased to have my call answered right away by a very friendly gal who took down my information and confirmed a time for me a few days later.

Loren arrived within 10 minutes of the start time of our appointment. He did great job and was tidy. I'm sure you can find someone cheaper - but my time has value and Loren and Thoma electric did a solid job, on time, and professionally.

I would use them again for my home repairs and upgrades.

Gill from Thoma Electric came to our home today and helped us out big time! He was so friendly, kind, and helpful. We just moved in and had several outlets that weren't working. He got to the bottom of all problems and fixed everything, and was a pleasure to have in our midst all the while! If everyone was as friendly and helpful as him, this world would surely be a better place. He truly went above and beyond and was also completely professional! I signed up for yelp to write this review, and I hope lots of people see it. Thanks Gill and Thoma! Couldn't be happier.

We had a huge list of upgrades to our home done by Lauren and John. This involved upgrading lights to LED, replacing smoke detectors, upgrading thermostats, installing plug, installing a bathroom heater, and fixing all the bad things the builder did when they built our house in 1996.

The guys did a great job and left the work area clean. We had a couple of set backs in the project where we wanted a light in a specific location but they could not put it there because of the way the house was built. This had nothing to do with the work they did it was just one of those things that happens in a Honey-Do list of 24 items.I was especially impressed with the communications from the guys on the overall job.

I would recommend Thoma Electric to my friends.
