Kristi “Sissy” Ouimet, 34, passed away on Thursday, February 26th, 2026. Kristi was a lifelong resident of Monson, MA and graduated from Monson High School in 2009.

If you knew Kristi, you know you could always find her laughing (witch cackling), singing at the top of her lungs for all to hear (really. really. loudly.), and spending time with her beloved family. She had a deep love of exploring the outdoors with her soul dog Hope, and the two absolute lights of her life, her son Bryson and her niece and goddaughter Rylee. They loved to do arts and crafts, ride their quads, kick her butt in sports, and most of all, make each other laugh. Kristi had a fully contagious laugh, and it will be one of the many wonderful things her family remembers about her forever.

She leaves behind her most beloved son Bryson of Spencer, her cherished niece Rylee, her dad, work buddy, and friend Michael of Monson, her treasured mom Claudine LaValley of Vernon, CT, her best friend in the world and sister Nikki (Ninnie) and her husband Chris (Kissifer) of Monson, her first special love, her baby brother Cam and his girlfriend Sarah of Vernon, CT, her loving step siblings Robbie and Julie, and her “niece” and great friend, Cindy. The best auntie ever will forever be missed by her other nieces and nephews, Jayne, Parker, Miles, Owen, and Kensleigh. She will also be missed by her dog Hope, and the other fur babies she loved, Cappy and Charlie. Her family and so many people will remember the absolute effervescent ball of sunlight she was, especially the Amsden, Hayes, Wells, and Esser families.

Services will be private and held at the convenience of the family. Wilbraham Funeral Home has been entrusted with the arrangements. In lieu of flowers, memorial contributions may be made to Massachusetts Organization for Addiction Recovery, 105 Chauncy St., Boston, MA 02111, Dakin Humane Society, 171 Union St., Springfield, MA 01105 or the National Pancreatic Cancer Foundation, PO Box 189, Box Elder, SD 57719.

The family would like to extend their heartfelt gratitude to Kristi’s coworkers at Adams and the people of Monson for their generous outpouring of support and love through this difficult time.
