Kathleen is an award-winning artist with a passion for watercolor painting and life! Painting in the studio as well as Plein Air (outdoors on location), she immerses herself in the fluid and unpredictable qualities of watercolor paint to capture the brilliant light and colors of nature.

Kathleen paints in a realistic painterly style, bringing the effect of changing light and color that describes the atmosphere, context, and shape of the scene to the paper.
