Kosiorek, Jr., died peacefully on September 16, 2021 at the Shady Knoll Health Care Center, Seymour, with her family by her side.

Jeannine, a resident of Beacon Falls since 1973, worked together with her husband as the owners and operators of J&J Pet Service, dog groomers. Mrs. Kosiorek was a gifted groomer and maintained a large customer clientele for many years, until the time of her retirement. Many clients were saddened when she retired. Her love for animals was unparalleled, she was a member of the CT Humane Society and the ASPCA. Jeannine enjoyed gardening and participated in functions at the Beacon Falls Senior Center. She loved her home, being with family and attempted to make everyone happy. Jeannine was competitive in playing cards, board games and yard games and hated “hated” to lose. She was known for her bountiful vegetable garden that produced 100’s of canned tomatoes, pickled beets and pickles. Her talents in the kitchen seemed endless! She baked the best apple and pumpkin pies, whipped up pancakes and crepes with berries, and indulged in ice cream. Jeannine was always very particular with her hair. She loved to talk on the phone, watch medical TV shows, the Lifetime and Hallmark channels, as well as Christmas movies. Jeannine made many new friends at Shady Knoll; there she’d play bingo, enjoy the outdoors and the musical entertainment. She will be long remembered for her special love for her family and many friends.
