Peter Walsh characterizes himself as part-contractor, part-therapist. He has been an organizational consultant for the past 12 years and his clients have included numerous Fortune 500 companies as well as scores of harried and disorganized individuals who want to de-mystify, de-clutter and re-organize their personal spaces. Peter holds a master's degree with a specialty in educational psychology and has been president and CEO of an international training and development company. When not wading through clutter and large-scale disorganization on Clean Sweep, Peter lives in Los Angeles — a long way from the small country town outside Melbourne, Australia where he grew up.
