Special Guest at the Philadelphia One Promise Gala Constantine Maroulis

Constantine first came to prominence as the beloved rock n’ roll underdog on American Idol. He then secured his place in pop culture as a Broadway superstar, best known for his TONY-nominated role in Rock Of Ages (in which he sang Don’t Stop Believin’, which is the theme of our gala). Now, for his third act, he begins an invigorating and promising new era with a bevvy of intriguing projects, including putting the finishing touches on his most assured and swaggering solo music to date. Constantine will be joining the Breakthrough T1D family at the 2017 One Promise Gala being held at the Hyatt at The Bellevue on May 20, 2017!
