Pierre was born on March 28, 1963 in Brussels, Belgium, from the love of Claire Capron and Jacques Massion, his proud parents. He grew up happily in the Brussels district of Stockel, avenue des jockeys 13, the third of five children including his two older sisters Anne and Brigitte, followed by his sister Catherine and brother Paul. An impressive baby, strong and smiling boy, Pierre soon developed an incredible sense of humor and an affinity for sports. Pierre was both a force of nature and a lover of nature, with his heart in the mountains. He had peaceful and humanitarian qualities, sensitive to the social injustices in our world. He became involved with Amnesty International fighting for human rights in his high school years and went on a transformative trip to Rwanda that shaped his desire to lend a medical hand to all walks of life.
