Peitsa, our owner started his journey in the construction industry alongside his father. Both hail from Finland and maintain the legacy of skilled craftsmanship and commitment to excellence. During the 1980s, he learned electrical skills from nearby professionals and established SESCO Electrical in the year 1992. Initially focusing on seismic safety and electrical work, by the end of the 1990s, the business had grown into solar energy and electrical work as it operates today. The company became incorporated in 2005 and added Regina Gilligan, his partner, as a co-owner. Now, in the year 2020, Peitsa and Regina are set for the next phase of life and have transferred ownership SESCO Electrical to two dedicated employees, Virginia Gonzalez and Hugo Lopez.
Virginia Gonzalez grew up the Bay Area and is a single mother of three amazing boys. Hugo Lopez comes from Guatemala and has more than 35 years of experience as an electrician. Hugo is proud to be a co-owner of SESCO Electrical. With years of service at SESCO, he is happy to continue the mission of SESCO.

Recommended Customer Reviews

We had them scheduled today to stop by one of our customers location at around 10:30 - 11:00 AM. We have called them, txted them yet no response. BEYOND UNPROFESSIONAL and I would never use them again. Idk how they have 4 stars.

Sesco successfully tackled a challenging problem of running fiber optic wire through a conduit that stumped the Sonic installers. Virginia, the office manager, arranged for Hugo to drop by first to make sure he could do it, then they both came back with another person a few days later and together they accomplished the job in half an hour. Although he couldn't pull off the same magic for a neighbor's longer conduit run, I was quite satisfied. Other electricians told me they would not even try to do the job at all or quoted me a minimum 2-hour charge.

This was the 6th apartment that Sesco Electrical upgraded for us and as usual they were efficient and professional. It was a pleasure to deal with Hugo and his crew as well as Virginia, their competent secretary.
If you are looking for a knowledgeable electrical firm, no need to go elsewhere.

Excellent service. Needed front porch light changed with added feature. Office returned call with a suggested appointment time. Confirmed and received call from the office when electrician was on his way. Job went smoothly and totally satisfied.

Absolutely amazing!! Virginia went above and beyond to keep me updated on the techs arrival. They needed 20 plus foot ladders down flights of stairs to change out our living room smoke detector, as we live in the hills. There were 7 more besides that one on various floors. The guys were absolutely the best electricians I have come across, courteous, hardworking, wearing masks during the heat. Highly recommended Sesco Electrical!!!

Hugo is the best electrician I've met. He came up with solutions that other electricians didn't, and his options were more affordable. Also, he knew how to add new electrical receptacles without damaging the wall, which minimized the cost for wall-patching work. He knows what he's doing. He's professional and down-to-earth. I cannot be happier.

I have used twice now for electrical work.
Always great service.

Hugo and his assistant did a great job in rewiring and fixing our botched recessed lighting. They provided recommendations on the easiest way to fix it all and got the job done quickly.

GREAT experience! The technician showed up on time, was polite, professional, skilled and confident! Quickly diagnosed the problem and recommended a less-costly repair option. He let me get the needed part (new 240-volt outlet and plug) and waited until I got back. The repair is solid and works well and he UNDERCHARGED for the 2-hour job!!! Great service!!!

I tried to replace our under-cabinet lighting in the kitchen with some newer LED ones. Something went wrong during the process and half of the lights did not work.
Hugo came by and diagnosed and fixed the problem in one morning. Could not be happier.
