Abacus originally entered the marketplace as a commercial janitorial and maintenance service provider in the Baltimore-Washington corridor. More than seven decades later, Abacus is now a complex organization with locations across the United States and offers a rich variety of corporate services to customers across many industries. We specialize in providing best-in-class temporary staffing services, security services, and facilities management services to our customers. Our continued success is a testament to the dedication of our service workers, the value of our services and vision of our leadership.

Abacus was founded more than 70 years ago by Jesse McGee.  Following the same principles that we were founded on – hard work, dedicated service and relationships of trust – we continue to be owned and led by the McGee family.  We are headquartered in Baltimore, Maryland with a continuously growing network of regional and district offices supported by recruiting centers and on-site offices across the nation.
