Cesar Millan, (born César Millán Favela; August 27, 1969) is a Mexican American dog trainer. A self-taught expert, he is widely known for his television series Dog Whisperer with Cesar Millan, broadcast in more than eighty countries worldwide from 2004 to 2012. Prior to The Dog Whisperer series, Millan focused on rehabilitating especially aggressive dogs and founded the Dog Psychology Center in South Los Angeles (2002–2008) — under construction in a new Los Angeles location as of late 2009.
Millan's first three books, including Cesar's Way, all became New York Times best sellers, have cumulatively sold two million copies in the United States, and are available in 14 other countries. In 2009, in conjunction with IMG, Millan introduced a monthly magazine also titled Cesar's Way — with The Wall Street Journal reporting at that time that half of American consumers recognized Millan. With Ilusión Millan, his former wife, he founded the Cesar and Ilusión Millan Foundation – since renamed the Millan Foundation. He is working with Yale University to create a children's curriculum based on his work.
Millan's most important tool in both his success with dogs and business has sometimes been attributed to a personal sense of balance. The New York Times said that he "lives in the now and maintains a sort of über-balanced mien".
