The Castagna Realty Co. Management Team

Frank and Rita Castagna

Along with his wife Rita, Frank Castagna (1928-2020) was principal of Castagna Realty Company. After receiving his degree in civil engineering in 1950, Frank joined his father’s successful construction company, Gerace and Castagna Inc., as an assistant field engineer. 1955 saw the purchase of the property now known as Americana Manhasset, and in 1965 the firm’s name changed to Castagna and Son, Inc. Frank eventually took the reigns, steering the company toward continued growth. He subsequently led the company’s strategic shift in focus, beginning in the 1980s, to the development and management of quality real estate properties under the banner of Castagna Realty Company. Rita and her daughter Catherine are the current principals of Castagna Realty Company.

Frank and Rita were always involved in many charitable endeavors and organizations, including North Shore Child & Family Guidance Center, Northwell Health System Partners Council, The Viscardi Center, Momma’s House, Tilles Center for Performing Arts, Nassau County Museum of Art and Old Westbury Gardens. Together and individually they received honors from The Safe Center LI, St. Francis Hospital, Nassau County Coalition Against Domestic Violence, AJC, Maurer Foundation for Breast Health Education and Sid Jacobson JCC, to name a few. Together with her daughter Catherine, Rita continues the mission of philanthropy that she and Frank established.
