About us

Ms. Silvia Guerrero, President of S&G Janitorial Services immigrated to the United States on 1991. 5 years after her arrival, she immediately started a residential cleaning service, servicing residents on the Peninsula in San Mateo County. S&G grew quickly as residential business, employing five full time employees, including herself. S&G residential business was severely affected by the downturn in the economy, reason for her to redirect her business focus to commercial properties, where she could still remain in the same industries providing a similar type of cleaning, but retaining all her full time employees.

S&G Janitorial was an example of how a good business can form in the times of hardship. Silvia continues to educate her employees on how to improve the level of service, while overseeing every detail of the business. Silvia has built a family business that she is very proud of. S&G Janitorial Services plans to expand as a commercial service for other Class A Buildings in the Bay Area.
