    Voluntary and Civic Involvement

    Civic engagement has been a large part of Sarah’s life since high school. In recent years, she has been actively involved in her local civic association and college alumnae association.

    As president of the civic association, Sarah negotiated a merger with the local parks group and obtained 501(c)(3) status for the combined group. During her presidency, Sarah led the association through a controversial development proposal that ended with strong community support for a significantly modified project and a record contribution from the developer to support the association and local parks improvements. Sarah remains responsible for development issues for the association, working closely with elected officials on the impact of development on residents.

    As the secretary and career liaison for the Bryn Mawr Alumnae Association, Sarah was part of the board that provided continuity during a period of transition that involved the departure of the association’s long-term executive director and the launch of a new career center.


    Sarah lives with her husband in Boston’s smallest neighborhood in a house that used to be a classy nightclub. Rumor has it that Madonna and Liza Minelli have both had a cocktail after their shows in what is now Sarah’s kitchen. While she loves urban living, Sarah maintains a strong connection to her hometown in southern Maine where she gardens during the summer.
