The firm of Abato, Rubenstein and Abato, P.A. was created in 1984 by the merger of two firms, Abato and Abato, P.A., and Edelman and Rubenstein, P.A. Both firms represented numerous benefit funds and labor unions in the Baltimore area and surrounding states. At that time the Abato firm represented unions in construction, stevedoring, retail food sales, bakeries, distilleries, trucking, music and entertainment, manufacturing, chemicals, schools, and government. The Rubenstein firm represented unions in the garment, clothing and textile industry, transit, trucking, electrical generation and distribution, manufacturing, racetracks, and broadcasting. Both firms represented pension and welfare funds in these sectors and others.
Cosimo C. Abato and Thomas E. Bracken established the firm of Bracken and Abato in 1962. Anthony A. Abato, Jr. joined his brother Cosimo in the practice in 1965. The firm became Bracken and Abato, P.A. in 1970, then changed its name to Abato and Abato, P.A. in 1974 when Thomas Bracken left to become an administrative law judge.
