Not sure if you're in range?
Boeing-trained. Marine-disciplined.
EV-obsessed since 2018.
Ray Novelo was a satellite and radar technician in the U.S. Marine Corps, then a Boeing-trained electrical specialist — before a broken window regulator on his own car pulled him into the EV world. He apprenticed at Tesla-specialized garages starting in 2018, launched his own mobile service in 2023, and hasn't looked back. Every job gets a written report. Every price is quoted before work begins.
