WIN-WIN: As founder of the Newton-based nonprofit Discovering What’s Next, Carol Greenfield  has discovered that people over age 55 are excited to enter their “encore” stage of life, but find few opportunities that offer the meaningful, paid part-time work they are seeking. To fill this need, the Newton resident has taken on a new role as director of ReServe Greater Boston.  

Founded in New York City in 2005, ReServe is a program of Career Moves, a division of Jewish Vocational Service, that matches older adults with assignments in the nonprofit and public sectors that pay a stipend. With an average placement of three to 12 months, the positions are designed to be project-based with flexible, part-time hours.
