Joyce was an old soul, a special and highly creative, spiritual person, who was one of a kind! We were friends for many years, sharing happy times and memories together. We taught school together in Elgin, Illinois and had a cherished friendship. Joyce loved helping people especially children and adults who were struggling with life issues. She was dedicated to her many beloved pets over the years including her horse Duke and numerous cats and dogs. Heaven has welcomed another angel in our wonderful friend Joyce. RIP Joyce, you are dearly loved!
