“The Gateway to Southern California” Ontario is the economic heart of the Inland Empire Metropolitan Area, a region of sun-kissed valleys and rolling hills once famous for its vineyards, citrus groves, and grazing pastures. Today, the metro area is a major industrial and commercial hub, with over 8000 businesses based in Ontario alone. Add your name to the list with flexible, serviced office space at Palmetto Offices. Located close to the city centre, our fully furnished offices offer easy access to Interstate 10. Ontario International Airport is less than 10km away, and Downtown Los Angeles is 56km down the road.
