Polly Hanson, a 21-year veteran of Metro Transit Police in Washington, D.C., broke a glass ceiling for women today with the announcement that she will become her department’s first woman chief on July 1st. Hansen, 46, will lead over 350 sworn officers, and will oversee the safety of more than a million bus and rail customers, nearly 10,000 Metro employees, and a patrol area covering 1500 square miles. She is only the second woman in the U.S. to head the police department of a major transit agency. She joins Chief Mary Rabadeau, who is Chief of the New Jersey Transit Police, and was a speaker on preparedness for biological and chemical attacks at the recent National Center for Women & Policing 7th Annual Leadership Conference. The National Center congratulates Chief Hansen on her appointment, and welcomes her to the growing community of women chiefs!
