Harriet Binder’s leadership in Hadassah Needham is a 60-plus-year story of devoted service during which the 99-year-old held the positions of treasurer, vice president and president, among others. It has been in her role as chair of cards and certificates, however, that Binder has made her most significant contribution to the suburban Boston chapter. Ten years ago, she launched a Mother’s Day initiative that has raised approximately $500,000 through the annual sale of artistic, elegant paper certificates for the May holiday.

Originally supported in her efforts by her late husband, Milton, Binder now enlists her daughter, Karen, and son, Rick, to help her design the different floral motifs for the certificates as well as package and mail them.
