Cepheid: Lodi’s Largest Private Employer Is Also One of the World’s Most Important Medical Companies

On May 28, 2026, Cepheid held the grand opening of Building 5 on its North Guild Avenue campus — the final phase of a multi-year, $200+ million expansion that has made Lodi the company’s primary U.S. manufacturing hub. Cepheid makes the diagnostic test cartridges used in more than 180 countries to detect tuberculosis, COVID-19, MRSA, HIV, and dozens of other infectious diseases. It is a wholly owned subsidiary of Danaher Corporation and is Lodi’s largest private employer. Roughly 40% of Cepheid Lodi jobs pay at or above the Lodi median household income as a single earner’s salary — an unusually high proportion for a Central Valley manufacturing campus. The company is navigating a leadership transition following President Vitor Rocha’s April 2026 departure.
