Mark Tatulli, who was first known for his "Heart of the City" comic strip, took on "Lio" as an outlet for his dark and twisted humor. In addition to his cartooning experience, Tatulli is also an accomplished filmmaker and animator, and is the recipient of three Emmy awards for his television work. Mark currently resides in New Jersey with his wife, son, and two daughters. His children are the true joy of his life and the inspiration for much of his comic artwork.
