A 25-year veteran with Brown Harris Stevens, Phebe Bowditch is a member of the Real Estate Board of New York (REBNY). She specializes in high-end co-ops and condos in some of the most prestigious buildings on the Upper East Side, including Park and Fifth Avenues, as well as Central Park West and Gramercy Park. A 1954 graduate of Vassar College, where she majored in political science, and mother of two -- Richard, a professional photographer, and his sister, Lowell, a University of Oregon classics professor -- Mrs. Bowditch joined Brown Harris Stevens in 1973. She had earlier been with Merrill Lynch as a writer and editor of business publications. A member of the Cosmopolitan Club, Mrs. Bowditch lives in a terraced apartment on the Upper East Side where she cultivates her garden. An accomplished equestrian, she may be the only residential broker in town who lists, among her varied outside interests, "fox-hunting."
