Diane Keane, a native of Turtle Creek, PA, has been making art since childhood. She completed a year at Carnegie Mellon University as a graphic design major in 1969 before leaving to marry and start a family. Post-marriage, she obtained a commercial art certificate from the Art Institute of Pittsburgh in 1982 and worked as a commercial artist, graphic designer and calligrapher in both free-lance and employed situations. In the 80s she began exhibiting hand-made paper collages, cast-paper sculptures, and assemblage boxes at various venues, including Pittsburgh Center for the Arts and the Southern Alleghenies Museum of Art. 

From early 1991 through 1999 Ms. Keane lived in Germany as a military spouse and civilian employee with the U.S. Army. She continued to pursue her art and exhibited work in Mannheim, Germany and London, England, among other locations. In 2000 she returned to the Pittsburgh area to care for her elderly mother. In 2010, she began a collage-a-day project and created a blog, Collagitation, to post her work online.  

Ms. Keane retired in 2017 to make art full-time. Her primary medium is assemblage, but she has also exhibited collages and acrylic paintings. Most recently, she has exhibited at Irma Freeman Center for Imagination, Boxheart Gallery, Spinning Plate Gallery, and at the Stifel Fine Arts Center at Oglebay Institute in Wheeling, WV. She is a member of the Pittsburgh Society of Artists and the Pittsburgh Calligraphy Guild.
