Katherine Liontas-Warren has been a resident of Oklahoma since 1984, where she dedicated 37 years to teaching printmaking, drawing, and watercolor as a professor of art at Cameron University. She retired in May 2021 to focus on her career as a full-time professional artist. She holds a Master of Fine Arts degree from Texas Tech University and a Bachelor of Science degree from Southern Connecticut State University. In recognition of her contributions to art and education, she was honored with the Oklahoma Governor's Art and Education Award in 2014 and named Artist of the Year by the Paseo Art Association in Oklahoma City. Liontas-Warren has exhibited her artwork in over 400 national and international solo, invitational, and juried competitive exhibitions, earning numerous purchase and juried awards. Her artistic journey has continually evolved, reflecting themes of time, movement, and transformation. Water, a recurring element in her work, symbolizes a desire for change and discovery, serving as a metaphor for her emotional and universal experiences. Through oils, gouache, watercolor, and printmaking, she explores themes of romance and dynamic, imagined seascapes. The fluidity of the sea and the patterns in her lino prints capture the rhythms of nature, while stormy sunsets and waves narrate the passage of time, celebrating the inevitability of change. Her prints and drawings are held in the permanent collections of numerous prestigious institutions, including Austin Peay University, the Arkansas Art Center, the Wichita Falls Museum of Art at Midwestern University, Oklahoma State University, the University of Louisiana at Lafayette, the University of Colorado, the University of North Dakota, and the Milwaukee Museum of Art, among others. Most notably, the Museum of Texas Tech University recently acquired 86 of her works for the Artist Printmaker Research Collection, a significant documentation of American artist printmakers.
