She and her husband Brent were long-time parishioners’ of St. John Vianney Catholic Church where she sang in the choir. Cynthia was a positive, energetic person who always saw the good in all of us. She was appreciative of the beauty that God gave us. Her husband acclaimed that Cynthia’s most outstanding quality was that she could see the good and beauty in everyone she ever met, even when they couldn’t see it in themselves. She loved all animals especially horses, to which she was an excellent competitive equestrian rider, & her beloved pet dachshunds. She loved attending all sporting events & being with her friends in the St. John Vianney Catholic community as well as those at St. Faustina Catholic Church.
