Mellon is well known for his portrait busts, commemorative statues, and works in bronze exploring the worlds of dance, sport, and family life. Mellon’s works in museum collections include the 2009 Official Barack Obama Inaugural Medal and bronze busts of George H.W. Bush. His portrait bust of Pope John Paul II resides in the Papal Apartments of the Vatican; his bust of Elie Wiesel is on view at the 92nd Street Y in NYC and the Wiesel Center for Judaic Studies at Boston University. In 2018 a monumental version of Mellon’s Wiesel bust was unveiled in Elie Wiesel Plaza, Bucharest, Romania.
