Bret Iwan has loved the legacy and story behind Walt Disney for as long as he can remember, but he never dreamt life would take him to where it has; voicing Walt’s most iconic character, and carrying on a legacy he has always held in great esteem. After graduating high school in 2000, Bret decided to pursue his love of art and animation. Bret earned a Bachelor of Fine Arts Degree from Ringling College of Art and Design in 2004, before moving to Kansas City where he started his career at Hallmark Greeting Cards. Just before Bret's fifth anniversary with Hallmark, he received an email from a college friend, a PIXAR animator, outlining the auditions that were being held to select an understudy for the voice of Mickey Mouse. Realizing the chance of a lifetime, he didn’t hesitate before practicing and submitting his audition. After several auditions, Bret was awarded the role as the fourth official voice of the beloved character, Mickey Mouse, a character first voiced by Walt Disney in 1928. Bret moved to Los Angeles in September of 2009 to start the next chapter of his creative career. His first recording was in June of 2009, and since then, he has gone on to record for theme parks, video games, toys, promotional material, game shows, live shows, ‘Mickey Mouse Clubhouse’, and ‘Mickey and the Roadster Racers’ television series.
