She worked for Empire Blue Cross Blue Shield for nearly 43 years, retiring as an Executive Assistant to the President of the company. Rose Marie retired with her beloved Louie to travel and to spend more time with her family. Together, they spent many wonderful weekends and vacations in Point Pleasant Borough, NJ with family and friends, old and new. Rose Marie would be described by anyone who knew her as a classy lady: hair done up, make-up perfect and dressed to the nines. She enjoyed music and dancing, socializing and laughing, cooking and caring. A piece of you will always be with us, and all who called you Nanny or Aunt Rose Marie.
