By ED BARMAKIAN, CHATHAM, NJ - "My name is Tayfun Selen. I'm the mayor of Chatham Township." Those words brought applause from the packed crowd in the Chatham Township Municipal Building meeting room on Thursday night when Selen achieved what he described as the "American Dream" after he was voted in as the new mayor of Chatham Township and sworn in with the help of former Lt. Governor Kim Guadagno. An immigrant from Turkey, Selen came to the United States 22 years ago, starting out as a gas station attendant with little mastery of the English language. It was noted that he is not the first Turkish immigrant to serve Chatham Township since Turkey native Rustem Bey served as the township's very first police chief.
