When Clarita Perez de Alejo retired four years ago from the corporate world, she traveled extensively and spent time with her grandchildren.
"I kept thinking, 'What else can I do?'" she said. "I felt I had a lot to contribute. I still wanted to help out."
In November, Perez de Alejo, 66, found a place where she can use a lifetime's worth of skills. Through staffing organization ReServe, which pairs older executives and professionals with nonprofits, government agencies and public institutions, she began working at a West Kendall, Fla., high school, helping college adviser Maria Mendoza prepare more than 750 seniors for the college application season.
