Denis C. Mousseau
Denis C. Mousseau, 66, of Kansas Avenue, passed away unexpectedly, Oct. 18, 2019, in Australia, where he and his wife Shannon were vacationing on a trip of a lifetime.

Denis served his country in the United States Marine Corp. from 1972 to 1975 as well as retiring from the United States Army following 27 years of service.
He was a giving and generous man who dedicated his life to helping those in need, especially fellow Veterans. Denis was a member of the American Legion Post 1619, an active volunteer for the North Country Honor Flight as well as a volunteer and officer for the North Country Veterans Association.

Apparently God needed another good one and he got one of the best when Denis went home to Him. Denis was one of the kindest, most respectful men with whom I ever worked. God bless him and keep his family, whom he loved dearly, happy knowing their dear Denis will be watching over them.
