Leslie is a Mexican dubbing actress, singer, and digital animator who started his career in 2015. He entered the world of dubbing after being discovered by Raúl Carballeda through a fandub of a song he had made from the movie Anastasia. Although Carballeda invited him to do a voice test and tutor him, Leslie felt it was too late to enter the voice-over industry. However, years later, at the end of his Digital Animation degree, he decided to give dubbing another chance and contacted Carballeda, who was in Europe working on other projects. With the help of well-known people inside the industry, Leslie got started with making room for himself in the world of dubbing. He then participated in an animated series and began reporting to other directors and studios, eventually making dubbing a permanent job along with digital animation.
