Workshops & Retreats

Anna Koster

Anna Koster has enjoyed a full life focused on art. In 1976, she had the opportunity to serve as Georgia O’Keeffe’s weekend companion. She went on to earn a Master of Fine Arts degree and teach at the Community College of Denver, San Jose Museum Art School, and other venues through the 1980s. At the same time, her career as an artist progressed with solo and group shows. Then she began working in art museums, completing a 35-year career in California, with the final 15 years at Stanford University’s Cantor Arts Center.

She has been leading workshops at Ghost Ranch since 2014. In recent years, the Georgia O’Keeffe Museum (Santa Fe), Nevada Museum of Art (Reno), and the Palo Alto Art Center (California) have offered Anna’s classes. Her positive, affirming approach to teaching, combined with insights from O’Keeffe’s art and life have earned praise from participants: “uplifting,” “inspiring,” and “amazing.” See more at

Anna’s own work includes super-realistic and trompe l’oeil (trick-the-eye) painting as well as drawing and conceptual art projects. Visit to view Anna’s art; her resume is at
