After a strong fight against metastatic breast cancer, Michelle (Dupuis) Tetreault, 61, of Groton, CT passed away peacefully on Dec. 13th surrounded by her family. Michelle was born on June 20, 1960 in South Hadley, MA. After graduating from South Hadley High School in 1978, she went on to study social work at North Adams State College. After marrying Kerry in 1983, she had two daughters that she loved fiercely. In Michelle's own words "my daughters were the best thing I ever did". Michelle enjoyed vacationing on Cape Cod, watching the Patriots (before Tom Brady left), and long walks on the beach, especially in the winter. Some of her favorite things were cape cod potato chips, lobster dinners, oysters, and spending time with her granddogs Oakley and Rusty. She fought hard to be able to dance with her daughter at her wedding this fall. She recently retired from Electric Boat in Groton, CT where she made countless friendships. She was a force to be reckoned with, she left a lasting impression on everyone she met. We will never be able to fill the space left behind by her. Michelle was predeceased by her father Richard Dupuis of Chicopee, MA. She is survived by her mother Barbara (LeGrand) Yates, her brother Richard Dupuis of Chicopee, MA; her daughters Nicole Tetreault of Swampscott, MA, and Brianna (William) Borg, of East Hampton, CT; their father Kerry Tetreault of East Haddam, CT; and countless family members. In lieu of flowers, please consider making a donation to Dana-Farber Cancer Institute or METAvivor in Michelle's honor.  The funeral will be Monday December 20 ^th starting with visiting hours from 9:00 am to 11:00 am at The O'Brien Family Funeral Home 33 Lamb St., South Hadley followed by a funeral mass at St. Patrick's Church, 30 Main St., South Hadley, MA at 11:30 am.
