GMI understands that standardization and systemization generate consistent service levels. That is why we employ the innovative, high-performance cleaning process known as Operating System 1, or OS1. OS1 is the only certified ISO 9000 certified cleaning program available and GMI is the first certified OS1 service provider in California.
