About SSO LLC,

Founded in 1999, SSO has been a leading provider of custom fabricated products and services to all of South-Eastern Wisconsin. With over 40 years experience we are able to provide both in-house and on the site fabrication requests.

SSO, LLC was started in 1999 by founder and owner Scott St. Onge.  Scott started in the sheet metal and fabrication industry at the age of 16 and quickly developed a unique expertise in all facets of the industry from welding and fabrication to field measurement and installations including project management.  At the age of 23, Scott completed a sheet metal apprenticeship.  After 25 years of traveling around the United States performing various jobs and installations, Scott decided to take his expertise and dedication to quality and accuracy and start his own business.  Scott started with a pickup truck and gas welder performing field work jobs and installations.  As demand for his services grew, he moved his operations to his current location on the north side of Milwaukee where he expanded his equipment and fabrication capabilities.  With over 40 years of experience, Scott continues to provide custom fabrication solutions at the industry’s highest standards.
