He has a fine art degree from the University of Utah with graduate studies in painting, drawing and portraiture. He studied under great Utah artists such as: Alvin Gittins, V. Douglas Snow, Ed Marion, George Dibble and others. Through the years, he has also been a television and film designer having worked with and sold paintings to such luminaries and collectors as: Judith Anderson, Ray Bradbury, Jack Brodsky, James Coco, Terry Garr, Peter Graves, Lorne Green, Mary Hart, Bob Hope, Alfred and Alma Hitchcock, Celeste Holm, Bon Jovi, Carol Lawrence, Rita Moreno, The Osmonds, Debbie Reynolds, John Schlesinger, Barbra Streisand, Danny Thomas, Dick Van Dyke, Ben Vereen, Frank von Zerneck, Barbara Walters and many others.
Seven is a widower with three lovely daughters and 13 beautiful grandchildren. These days, he can often be found in his Provo, Utah studio happily painting mining-town motifs and enjoying his family's western heritage.
