Trusted since 1974
In 1974, Pete Sherman founded Shermco from humble beginnings, repairing generators for aircrafts during the Vietnam War. Pete used to tell the story that, at one point, likely every B52 in the U.S. fleet had a generator serviced by Shermco. His dedication to exceptional quality and personal service transformed single-job clients into long- term partners, paving the way for Shermco to become a nationwide leader in electrical services.
