About Us
Our Beginning
Longden Test Only is a family-owned smog shop built from the hard work and determination of a family who came to the United States as immigrants seeking better opportunities. Starting with limited resources but a strong commitment to honesty and quality service, they gradually built a trusted local business that puts customers first. Over the years, Longden Test Only has become known for its integrity, fairness, and friendly atmosphere—values rooted in the family’s journey and appreciation for the community that supported them. Today, they continue to provide reliable test-only smog inspections while maintaining the same dedication, humility, and work ethic that shaped their beginnings.
