"Harvard supports the mentor program," she said.
The event also featured guest speakers Dr. Deborah Sichel and Jeanne Watson Driscoll, who recently co-authored a book on women's moods.
Towards the end of the celebration, Piltch and program committee members lit the candles of a cake and sang "Happy Birthday to us."
Piltch said she hoped the Radcliffe Mentor Program would celebrate many birthdays in the future.
