Our Story

At the young age of 14, Xavier Garza entered the electrical trade in 1976 as a helper. Ten short years later, he was a master electrician. He was in the union for seven years traveling to Costa Rica, California, Arizona, the Texas Panhandle and New Mexico.

“I gained so much experience working as an electrician,” says Garza. “I worked in the oilfields and refineries in the Odessa-Midland area, five years in Rio Rancho, NM working at Intel’s Fabs. 7 thru 11, as well as, at Intel’s chip assembly plant for in Costa Rica.”

In January 2005, Garza was working for an electrician in Georgetown when he got the vision and fortitude to start his own company, Sierra Electrical Services as a one-man shop out of his garage in Georgetown, TX. Two years later, Garza brought in his nephew, Rene Garza. Together, they slowly started growing Sierra Electrical Services doing home warranty service work.

By the company’s third year, Garza got an office he shared with a plumber friend, L & H Plumbing. “We just slowly started growing from there,” adds Garza. “We were probably doing anywhere from a few hundred dollars to a thousand or two dollars a week then. Now we average about two to three million a year.”

In 2023, Sierra Electrical Services relocated to Cedar Park and recently move into their current location in Round Rock, TX.

“We had always did well when we officed off I-35. We had jobs in San Antonio, Corpus Christi, Wichita Falls, Jarrell, and all over,” states Garza. “Our Cedar Park location was off the beaten path and we realized right away it was easier to office along the I-35 corridor. So, when our lease ended, we moved to Round Rock. Now we are, again, off the I-35 corridor at 200 Main Street, Suite 109.”
