One of Sue’s great loves is music. She attended the MacPhail Center for Music in Minneapolis and has recorded a handful of jazz tunes. Ask her to sing a tune the next time you chat with her on the phone!

Sue is originally from Minnesota and moved to Colorado to be closer to her son and to escape the mosquitoes, high humidity, and long winters that Minnesota is known for. She loves spending time with her family, hiking, camping, singing and listening to music. One of her most memorable travel experiences was visiting Yellowstone with her husband, son and mother-in-law.
