Jan attended the University of Oklahoma where she majored in commercial art. After college, the following sixteen years were spent on the East coast, where she married and began raising her family. Jan studied portraiture with Daniel Green at the Art Students League in New York City and was a member of the National Guild of Scientific Illustrators and the Women's Caucus for the Arts, as well as several other art societies in the East. After a successful exhibit in the Cork Gallery at Lincoln Center in New York City, she headed back to her beloved West. She is currently a member of the Pastel Society of Colorado, Pastel Society of New Mexico, American Women Artists, the Tubac Center of the Arts, and a Signature member of the Pastel Society of America.
Jan's varied career included magazine production in Odessa, Texas; fashion illustration and hospital public relations in El Dorado, Arkansas; and jewelry manufacturing in Albuquerque, New Mexico. After fifteen years in the jewelry business, Jan and her husband sold the business and “retired” to Creede, where they opened the JThompson Gallery and Lovering's Bead Loft. They sold the bead business in 2007 so Jan could hold summer pastel painting workshops above the gallery. Her popular classes are becoming a summer destination for students to enjoy the mountain scenery. Jan's original pastels and prints reflect the beauty of her mountain community and the western way of life. Her award-winning artwork is becoming highly collectible, especially her signed limited edition prints
