Son of Michael and Cindy Flagg, and grandson of Edith Flagg, Josh grew up in Los Angeles' Westside. He graduated from Beverly Hills High School in 2004 and jumped right into high-end residential real estate. As one of the stars of Bravo's "Million Dollar Listing," Josh's reputation in luxury real estate has become renowned around the world. Flagg does more than sell real estate though. He is also an art collector, and has collected since he was 15 years old.
