Early life
Léo was born in São Paulo, Brazil, but moved to New York City as a young child. He learned the piano as a child, but as he grew up, he was more interested in playing the guitar and beatboxing. After his father was transferred to Diamond Bar, California, Léo attended Diamond Bar High School. He was discovered when he was teenager by a producer who worked with Sabrina Mendes, founder of SM Entertainment. After auditioning for Sabrina and sending in demo tapes, he was signed to his newly established label, and moved to São Paulo. Although Léo enrolled in a university when he returned to Brazil, he dropped out to focus on his career.
