Rob Biagi was born In Mt. Kisco, New York in 1972 and raised in Shrub Oak, New York, an unincorporated hamlet in the Town of Yorktown. He graduated from SUNY College at Oswego with a BA in Political Science in 1994 and then received his law degree from Brooklyn Law School in 1997. Rob went to work immediately after law school as an Assistant District Attorney with the Bronx District Attorney's Office. From 1997 to 2000, he prosecuted all manners of felony and misdemeanor crimes and spent the last year in the Narcotics Division, where he tried cases involving undercover police cocaine and heroin drug deals.

Rob Biagi fulfilled his commitment with the Bronx DA's Office and in early 2001 joined the Law Firm of Ohrenstein & Brown, LLP, whose offices were located on the 85th floor of One World Trade Center. On September 11, 2001, Rob was riding the subway on his way to work from where he lived in the Bronx when the planes struck the tower a few floors above his office. Moments after exiting the City Hall subway station - unaware of what was happening - he watched his burning office building collapse. He walked all the way home to the Bronx on what was the longest and luckiest day of his life. The firm lost two employees that day and ultimately relocated to midtown, Manhattan, where Rob continued to work as an Associate in insurance-defense litigation and NYS Banking Regulation. He left in 2005 and joined an in-house insurance-defense law firm with The Hartford Insurance Co. in midtown, where he continues to work to this day as a Senior Staff Trial Counsel.

Rob Biagi now lives in New Rochelle just off Pelham Road. He co-founded the Greater Pelham Road Association - a community organization of local coop and condo board representatives organized to share common ideas and concerns and to act a voice in city affairs as they affected the numerous cooperative housing units along the Pelham Road corridor. During that time Rob was elected and re-elected several times- and still serves - as Vice President of the board of directors for his 85 unit coop complex. He also became a District Leader in the New Rochelle Republican City Committee and is also currently a member of its Issues Committee. In 2007, Rob was appointed by former City Councilman Mike Boyle to a term on the New Rochelle Traffic Advisory Committee. He and his wife Flora were married in 2007.
