Her first hand knowledge of western lifestyle is realistically depicted in her art. This background is also evident in her paintings of Texas Wildlife done in their natural habitat, and in her rendition of the ever popular Texas Bluebonnet scenes. She began painting as a child, self-taught and working only in watercolors. As a teenager, a friend encouraged and helped her do one oil painting. Again she went through a long period of self-taught training, this time in oils. She later studied commercial art in college, and fine art under private instruction. Today she works in both watercolors and oils.

Exhibits include such important invitational shows as the National Cowgirl Hall of Fame at Fort Worth, Texas, annually in the Western Art Show sponsored by the Alamo Kiwanis Club of San Antonio, The First Atlanta Art Show, Augusta, Georgia; and in many other shows over the United States, on television and on a European tour sponsored by the Center of Studies and International Cultural Exchange in Italy.

Her works can be found in the National Cowgirl Hall of Fame, Dr Pepper Museum and Free Enterprise Institute, Waco, TX and in many distinguished private collections, including President and Mrs. Bush, former Texas Governors John Connally and Dolph Briscoe and their families, famed heart specialist Dr. Denton Cooley and many others.
