Natalie Sansivero, 46, of Grand Island, NY, passed away on July 23, 2025, in Niagara Falls, NY. Born in Niagara Falls, Natalie was the cherished daughter of Joseph (Lynne) Costa and the late Elizabeth Putzak (née Buffone) (late Jake) Putzak; and the adored fiancé of the late Jerome “Jerry” Williams.
Raised in Niagara Falls, Natalie was a graduate of the former LaSalle Senior High School. She worked for many years as a paralegal for attorney Michael Dowd in Lewiston, NY, and served as the Controller of Niagara Falls Coach Lines. She was also a member of the Buffalo Club and several civic organizations with her beloved Jerry.
Natalie possessed a radiant and magnetic spirit. Her beautiful personality was contagious, her kindness boundless, and her heart unmatched. To know her was to love her. Her greatest source of joy and pride was her children, Gianna and Louis, whom she loved dearly.
