PMM Companies is a leading provider of janitorial and maintenance services in the Washington, DC, Baltimore, MD and Boca Raton, FL areas. PMM Companies services over 350 facilities and employs over 1,000 people. Our beginnings, though, were much more humble. PMM began in 1977 when Potomac Minute Maids, Inc. (PMM) was founded. PMM was a small residential house cleaning company with a vision of superior service.


From the beginning, PMM’s strong business ethics have been reflected in the corporate philosophy: As a family-owned and operated company for 35 years, the values of respect, integrity, service and excellence remain the core beliefs of all divisions within PMM Companies. It is a credo that served PMM well as the company has evolved and grown to satisfy the ever-changing market and customer needs.
