Jose’s son Frank worked part-time with his father during his school years and joined the firm full-time after high school. Working quite literally from the ground up, Frank decided to take his father’s lead one step further and founded Preferred Building Services Inc. in 1988. As a new full-services janitorial company, Frank insisted that the organization pride itself on reliability and excellent service, backed all by his personal guarantee.
Over the next 20 years, Preferred expanded its operating areas and scope of services throughout the eastern United States. Today, we provide a variety of building services to our growing group of loyal customers. Cleaning over 20 million square feet on a daily basis, we tackle office buildings, industrial areas, retail shops, institutional facilities, and more.
