Dennis Doughty of Booz Allen Hamilton

Asked to discuss career milestones, it’s not uncommon for a top consultant to slice his career history into two distinct chapters: one before making partner, the other after.

Dennis Doughty, president of Booz Allen Hamilton’s worldwide technology organization, divides his career with the Berlin Wall or, rather, the year it fell. Prior to the fall, one of his primary clients was the National Communication Systems, a federal organization created to deal with the communication challenges posed by everything from hurricanes to nuclear war.
