After the September 11, 2001 attacks on the Pentagon, the Secretary of the Veterans of Foreign Affairs Office asked Matt Lamb to develop an art therapy program to help the individuals whose lives had been affected by the tragedy to work through their grief. In May of 2002, 38 participants gathered with Matt to outwardly express their negative emotions of pain and grief and subsequently work through them to find their hopes and dreams. These individuals accomplished this by painting umbrellas! A parade followed in Washington D.C. , with displays on Capitol Hill and a tour of the White House.
Since that time, over 2,000,000 individuals in 29 countries have participated in Lamb Umbrellas for Peace; including some the following: Argentina, Australia, Austria, Belgium, Brazil, Canada, Czech Republic, France, Germany, Greece, Ireland, Italy, Israel/Palestine, Japan, Lithuania, Luxemburg, Panama, Philippines, Poland, Slovenia, Russia, Singapore, Spain, United Kingdom, USA, Thailand and Vietnam.
