O’Hagan was born in Wiesbaden, Germany, and was raised in the United States. He enjoys working in several media, but his primary focus is in pastels and oils. Although he appreciates many different forms of art, his main interests include the paintings of several late 19th century American, French, Spanish, and Russian painters Continuous study of these painters has had a strong influence on O’Hagan’s own art. Constantly challenging himself has translated into a fulfilling career in fine art encompassing several one-man shows and participation in group exhibitions in the United States, Japan, China, Canada, and France.
