Desmon O'Hagen was born in Wiesbaden, Germany, in 1959, and was raised in the United States. He enjoys working in several mediums including watercolor, acrylics, charcoal, pen-and-ink, and monotypes; but his primary focus is pastels and oils. He feels that experimenting with a variety of mediums has helped him appreciate many different forms of art. This in turn enhances his own work. Constantly challenging himself has translated into a successful career in fine art encompassing several one-man shows and participation in group exhibitions across America including Denver Rotary Club's "Artists of America", Colorado Governor's Invitational Art Show, The Pastel Society of America, and Salmugundi Club in New York. O'Hagen has also participated in group exhibitions in Japan, China, and France. He is a Master Pastelist with the Pastel Society of America and is listed in Who's Who in American Art.

O'Hagen has won awards at the Pastel Society of America's annual shows in New York City including the Mrs. Pearl Kalikow Award, Hudson Valley Art Association Award, and the Connecticut Pastel Society Award.
