Welcome to the Gasser Building, the Napa Valley’s Premier office location. We have offices ranging from single-executive offices on up. All of our office leases are full-service leases which means the only additional cost you will incur is for internet, and janitorial in your space. Located on Soscol Avenue, between the South Napa Market Place and Downtown Napa, the Gasser Building is the home of the Gasser Foundation.
