Deborah Fellows received her bachelor of fine arts degree from Fort Wright College of the Holy Names after having studied in Italy. In the post-Vietnam era, she won competitions to create the Inland Northwest Vietnam Veterans Memorial, Montana State Vietnam Veterans Memorial, and Washington State Korean Veterans Memorial. At the same time, she created monuments for Boy Scouts of America, Bing Crosby, Adolf Coors, James Irvine, and Henry Kaiser.
In 2015, the state of Arizona commissioned her to create a monument of Barry Goldwater for Statuary Hall in Washington, D.C. In 2017, she completed a monument of Jim Bowie for San Antonio, Texas.
In 2008, the National Sculpture Society elected Fellows as a lifetime member. Her art has won numerous Best of Show awards at major art shows. In 2009, she was inducted into the Cowgirl Hall of Fame in Fort Worth Texas, an honor reflecting her past of growing up on a ranch and sculpting the Western world that she knows and loves.
