For as long as she can remember, Jennifer Knight has wanted to be two things: an attorney and a leader. But if current trends hold, by the time she hits the point in her career when she would typically take on leadership roles, the number of her female colleagues will have plummeted — or Knight herself will have stopped practicing law. In Colorado, the number of male practicing attorneys remains constant until retirement age, compared with the number of women, which declines sharply from decade to decade, according to a report by the state office of the attorney regulations counsel that included a snapshot of the state’s 2015 attorney census. The drop in the number of female attorneys is not new and is not unique to Colorado, experts say.
