Over 30 Years of Excellence!Many things have changed since the first cup of coffee was brewed and consumed. One of those is the beginning of Office Coffee Service (OCS). OCS is based on the concept that there is a simple and convenient way to handle the coffee break at your office or business establishment.This is the concept that prompted Robert R. Smith to start Coffee Break Service. The Company was built on the idea that everyone deserves a quality cup of coffee with the convenience of a service that's second to none. Serving over 2500 customers, we continue to grow by providing quality products and excellent service to our customers in Southeastern Michigan.
