Betty was an active community volunteer for many years. From her first floor apartment and porch in the Neighborhood Women Houses, accompanied by her faithful dog, Rocky, she functioned as a neighborhood ambassador, talking and listening to everyone, offering wisdom and friendship. A member of Neighborhood Women Renaissance Housing Board for ten years,
she also worked with Vista/Americord as a gardener. She took a special interest in maintaining the Neighborhood Women Houses garden, which was named in her honor. Elizabeth took charge of cooking for the annual community meeting as well as all the Neighborhood Women events. She volunteered at the You Can Community School program, where she encouraged youth to have self-respect and stay in school. Her memorial service in 2008 brought more people out than any other meeting. In her youth, she was known for her spectacular dancing with her partner, Jose.
The Elizabeth “Betty” Marrero Garden at the Neighborhood Women Houses earned its name in recognition of the energy and passion Betty demonstrated through her work and her important role as a social link that brought together the Williamsburg-Greenpoint community.
