After more than four years with Cumulus as Regional Vice President Chuck Bortnick tells Radio Ink he'll be leaving the company. No departure date has been set and Bortnick says he'll be taking a job outside the radio industry, with Transworld Business Advisors in Connecticut. Several other former radio executives work at Transworld, including Eric Straus and Cary Davis. Bortnick said, "I am excited to take my years of management experience and background to Transworld, where I feel I can bring a fresh perspective to business buyers and sellers. I have very much enjoyed my last 4 1/2 years with Cumulus. Lew, John and Jon have been great to work for."
