History and Diversity


Janitorial Services, Inc. (JSI) was started in 1970 by Ronald Martinez Sr (President) in Cleveland Ohio. He still maintains ownership to this day, along with his son Ronald Martinez Jr. (Vice President)

Since 1970, we have developed a reputation of being one of Ohio’s premier janitorial providers, offering high quality cost effective building solutions. As of today, we employ nearly 1,000 individuals. We have grown a diverse customer base of over 275 accounts, and we now service the entire state of Ohio. We also have capabilities of servicing national accounts. We are proud to be the preferred janitorial service to some of the area’s largest and most prestigious office complexes.

It is our company’s goal to provide customers with the best possible service on a nightly basis, proactively find solutions for our clients, and have a mutually beneficial, long term relationship.
