Former Boies Schiller Flexner deputy chair and co-managing partner Natasha Harrison is leaving the firm to start her own boutique, according to a source close to the firm.

Harrison previously announced in September that she was stepping down from the deputy chair role after having been elevated to the position following the departure of former co-managing partner Nick Gravante to Cadwalader, Wickersham & Taft late last year. Her departure was first reported by Bloomberg on Wednesday.
