He began at WBOS and continued at WMEX. He became a popular tastemaker and his radio show became a popular outlet for reaching the teenage audience in the 1950s and 60s. After a stint as a DJ at WRKO, Arnie transitioned to becoming a general manager of radio stations such as WBCN, WWEL and WXKS. In the early 1980s, John Garabedian (who worked with Arnie at WMEX) brought Arnie in as General Manager of V66. While Arnie was not a VJ, his involvement with V66, gave the channel some serious clout. After V66 ended, Arnie returned to WXKS. In 1997, he was one of 25 American disc jockeys saluted by the Rock and Roll Hall of Frame. In 2008, he was inducted into the Massachusetts Broadcasters Hall of Fame. Today, he is retired in Ogunquit, Maine.
