Quinn and his brothers went into care when their parents' violent marriage ended in divorce. After a number of foster placements, he wound up in an adoptive family where he was systematically abused, emotionally, physically and sexually, until he was literally kicked out of the house to fend for himself aged 17.
He has gone on to obtain a doctorate and is the executive director of ICARE in Hermitage, Tennessee, a child advocacy organization specializing in family violence and child abuse.
His early life is described in his book Cry Out.
