Benjamin Agosto was born January 15, 1982, in Chicago, Illinois and raised in Northbrook, Illinois. He is the son of a Puerto Rican father and a Jewish mother whose family has roots in Romania and Russia. Agosto attended grade school at the Chicago Waldorf School, then spent two years at Glenbrook North High School, and graduated with honors from Michigan's Groves High School in June 2000. He played in a high school jazz band.
Agosto lived in Detroit, Michigan from June 1998 and then Canton, Michigan before moving to Aston, Pennsylvania in the summer of 2008. He relocated to Lacey, Washington in September 2010 and to Scottsdale, Arizona in 2014.
Agosto started skating at age six, after receiving a pair of ice skates for his birthday, and started ice dancing at about age 12. Early in his career, he was coached by Susie Wynne. He skated with Katie Hill from 1995 to 1998, competing with her on the novice and junior levels, including internationally. They skated out of Midwestern Section. When that partnership ended, Agosto moved from Chicago to Michigan in 1998 in order to train under Igor Shpilband.
