Originally from the Soviet Union, Jack began his artistic training at the age of twelve when he entered the School of Painting for Young Artists in Soviet Armenia. He was later accepted at the Apramhamian Art Studio where he was schooled in traditional techniques for painting from life using conceptual and technical methods of Spanish, Russian, and French Impressionism. Known for his vibrant colors, his expressive and free brushwork, Jack's paintings are in numerous galleries on the east coast and in the collections of the Armenian Library and Museum of America.
