Obituary of Dennis G. Mattison Sr.


Dennis G. Mattison Sr., 68, a lifelong resident of Greenwich, passed away Tuesday, January 17, 2023, at Glens Falls Hospital, surrounded by his loving family.


He was born March 12, 1954, in Cambridge, NY, to the late Don C. and Shirley (Greaves) Mattison.


Dennis first and foremost was devoted to his family, as a father, grandfather, brother, and friend.  He was a 1974 graduate of Greenwich Central School.  He worked in various papermills throughout his life and retired from the Greenwich Central School District, with 16 years of service, working as a custodian. 


His favorite thing to do was spend time with his sons and grandchildren.  He was known to frequent Lynns Café for breakfast and socialize with his friends over coffee at Stewarts.  Family gatherings, 60’s and 70’s music and mowing lawns were a few of his favorite things.  Dennis will aways be known for his fun loving, strong willed, jokester attitude.


In addition to his parents, he was predeceased by his brother, Donald William Mattison, brother-in-law, Ronald Dewey.


Survivors include his sons, Dennis (Vickie) Mattison Jr. of Mechanicville, Rodney (Heather) Mattison of Easton and Douglas Mattison of Easton; siblings, David Mattison, Shirley Dewey, Timothy Mattison, Stanley (Sandy) Mattison, and Michael Mattison; grandchildren, Caleb, Tristan, Dylan, Kendal, Caitlyn, and Leah; sister-in-law, Chris Mattison; several nieces and nephews.
