Bill Mack (b.1949), born in Minnesota, is an American relief sculptor whose work combines low and high relief, incised lines, and elements in the full-round that create three-dimensional pieces. For over twenty years, he worked mostly as a commissioned artist. His commissioned work ranged from very small, low relief ingots and medallions, to often monumental sculptures. In addition to creating hundreds of works in traditional cast bronze, he also gained experience with more modern substances, including resins, urethanes, epoxies, silicones and acrylics. He has exhibited in galleries in New York City, Beverly Hills, Tokyo, and Frankfurt. His work is in the collections of President Clinton and former President Ford, among others.
