Karen Garrett is most frequently lauded for revolutionizing the post-modern sculpture material movement. She is widely credited for expanding its original premise beyond just the exploration of "modern" materials to the groundbreaking use of cardboard and resin in monumental figurative sculpture. She is credited for having established this medium as an accepted vehicle for exterior installation art.
A few of her notable exhibitions have been at museum venues such as the Cockrell Butterfly House, Houston Museum of Natural History, Blaffer Museum of Fine Arts, Philbrook Museum of Art in Tulsa, Dallas Contemporary and the McKinney Avenue Contemporary.
In the late 1980s, Karen graduated from Oklahoma State University with degrees in fashion design and sculpture. She received her graduate degree from the University of Houston’s sculpture program and was the only woman in her graduating class.
