Michael Klein is part of a group of American realist painters leading a movement hearkening back to the Renaissance and French Academic traditions. Klein has had five solo exhibitions in the Unites States from 2008 through 2015. He also participated in the American Chinese Oil Painting Artist League (ACOPAL), an exhibition held at the Beijing World Art Museum. His work has been published in numerous magazines, such as American Artist, American Arts Quarterly, and Fine Art Connoisseur. Klein was awarded the prestigious William Draper Grand Prize at the Portrait Society of America’s International Portrait Competition. The artist has recently embarked on starting a new company located in Raleigh, North Carolina. He and his colleagues have created an online series called The Line, featuring paintings by today’s living masters.

Klein was 19 when he began his serious training in classical ateliers. His first teacher was Richard Whitney, who was one of New Hampshire's most prominent portrait painters and a pupil of R.H. Ives Gammell. Klein continued studying in Minneapolis at the former Atelier Lack, which was founded by Richard F. Lack, a classical painter whose efforts were in part responsible for the revival of traditional painting in the United States. Seeking to broaden his education, Klein began studying at the Art Students League of New York, most notably under the tutelage of the late Nelson Shanks. In 2002, Klein entered what would become his final school, the Water Street Atelier (now Grand Central Atelier), where he apprenticed under founder Jacob Collins until 2005.

Klein is represented by Ann Long Fine Art (Charleston, SC), Collins Galleries (Orleans, MA), Legacy Gallery (Scottsdale, AZ and Bozeman, MT), Maxwell Alexander Gallery (Culver City, CA), and Palm Avenue Fine Art (Sarasota, FL).
