Longtime Muny CEO Denny Reagan to step down after 2021 season Denny Reagan is convinced that everyone has a Muny story. He feels this way because once anyone learns that he is president and CEO of the St. Louis institution, they are eager to share their story with him. âItâs just wonderful to hear them, they mean so much to me,â Reagan said. âIâm always the most popular guy at a cocktail party, thatâs for sure.â In an interview with The American, his infectious laughter was a constant. From the beginning it was clear that the joy and kindness that has become part of the Munyâs organizational identity starts at the top.
