Judge Robert E. Antonacci: Professional Background and Legal Expertise

Biography

Hon. Robert E. Antonacci, II is a justice of the Onondaga County Supreme Court in the Fifth Judicial District of New York. He was elected to the Supreme Court in 2019.

At the time, Antonacci was serving as a New York State Senator in New York’s 50th Senatorial District. He was elected to the Senate seat in January 2019 and stepped down to assume his position on the Supreme Court.

Antonacci received a B.S. in accounting from Le Moyne College in 1987. After graduating with his bachelor’s degree, he joined the accounting firm Ernst & Young and would later become a licensed Certified Public Accountant (C.P.A.) in 1990. He went on to complete a J.D. at Syracuse University Law School in 1992.

After law school, Antonacci entered into solo practice at his own law firm. In addition to his private practice (1993 to 2007), he served as a Zoning Board attorney (2004 to 2005), a budget officer (2006), and town comptroller (2007) for the Town of Salina. Then, in 2007, Antonacci was elected county comptroller of Onondaga County. He would retain this position in subsequent elections, resigning after his election to the New York State Senate.

He has taught as an adjunct professor in the Business Administration Department of Le Moyne College.

Antonacci has served as a board member of the Onondaga County Resource Recovery Agency. In addition, he is active in the athletic community, where he serves as a referee for high school basketball games as well as oversees a youth baseball league. He also played on two All World Softball Tournament Teams.

Born and raised in Syracuse, New York, Antonacci attended Our Lady of Pompei Grammar School and Bishop Grimes High School.
