On May 6th, after a battle with cancer, Nancy passed away in her home surrounded by loves ones.  We grieve for loss of Nancy, who owned and operated the marina after Jeff’s passing in 2016. 

Nancy was born in Waterville on Oct. 18, 1954.  The second girl of five, Nancy was a loving, devoted sister and daughter who grew up enjoying Maine’s pine forests, rivers, and lakes.  Nancy graduated from Lawrence High School in Fairfield in 1973 and in 1977 Nancy graduated from the University of Southern Maine with a degree in nursing. She began her career in Waterville at Thayer Hospital and soon met Jeffrey Armstrong whom she married in 1982.  

Nancy obtained her master’s degree in nursing education and continued her career at Pen Bay Medical Center in Rockport for over 30 years, working among colleagues and friends. Nancy and Jeff spent many happy years together, raising children, expanding their home in Thomaston, sailing in the Caribbean with loved ones and traveling the world. Nancy served on the Thomaston School Board and Harbor Committee and was an active member of the Thomaston and Mid Coast community.   
Despite a cancer diagnosis, Nancy continued to live a vibrant life surrounded by friends and family.  She greatly enjoyed running Jeff’s Marine, and working with local businesses, fisherman and farmers, and seasonal Maine residents.  Her passion for boating and the Maine outdoors inspired many around her.
