Ministry Director
During the early years of COLFS, Marianne and her husband Tom, volunteered as Confirmation Coordinators at their parish and were blessed to bring those teens to volunteer with COLFS. Last year, after 30+ years as a design engineer (BSEE with postgraduate work), Marianne dissolved her corporation to devote more time to family and sharing her gifts. Always having an interest in being more involved with COLFS, God had a plan and opened the door for her. Marianne has been married to her knight, (yes, a real knight, Knights of Columbus), for 35 years and they have one daughter, Abigail Marie. When not spending time with her family, she is eating dark chocolate, HeeHee!
