Born and raised in Burgettstown, Pennsylvania, a small town near Pittsburgh. He is the middle son of Petro and Despina Maropis and is very close to his brothers, Sam and Chris. Being an exceptional all-around athlete in high school (Burgettstown High-school in southwest Pennsylvania), it appeared Adoni would pursue a professional career in some sport. Turning down various athletic scholarships, he enrolled at West Virginia University and graduated magna cum laude with a Bachelors Degree in Business Administration. But, from years of being entertained by Adonis impromptu comedic performances and impersonations which began when he was a small child, his father, Petro, told him that the suit and tie of the business world would probably choke him to death and encouraged Adoni to give acting a shot. Surprised, yet intrigued at this suggestion, Adoni enrolled at a performing arts school, Point Park College (now a University) in Pittsburgh, and studied acting, dialects, singing, and a bit of dance. His first stage role was as a freshman, even though freshman werent allowed to perform at the time, where they needed him as an Arabian Carrier in The Nutcracker Sweet. Not only did Adoni get to flex his muscles in that role, but he also played the Jack-in-the-Box in the same production. Some of his other memorable plays and musicals were: Working, Evita, Getting Out, You Cant Take it With You, and Little Shop of Horrors where he played the man-eating plant, Audrey II. After three years of theatre at Point Park, with the help of his younger brother Chris, he headed for Hollywood. Although Adoni is truly blessed with a more than usual dose of athletic ability and creative talent, what truly makes Adoni stand out is that he is a Type 1 Diabetic, and has been since he was 18 months old. His parents were told he would be weak and sickly, and in and out of hospitals his whole life.
