Kathleen Marie Fesi

It is with heavy hearts that we announce the passing of Kathleen Fesi (nee Koss/O'Sullivan), who departed this life on April 15, 2026, at the age of 69. She was a beloved member of a large and devoted family.

Kathleen was the loving wife of Richard Fesi; cherished mother of Kelli (Tim) Janczewski and Ryan (Sam Rago) O'Sullivan; and step-mother to Melissa (Mike) Canning & Jonathan Fesi. She was a proud and loving grandmother to Lily, Jake, and Finley Janczewski, and Mickey Canning.

She is survived by her siblings: Sue (Ray) Lovato, Barbara (Tim Milet) Koss, Mary (Mike) Rohan, Nancy Koss, John (Sue) Koss, Genevieve (Brad) Hensley, Shirley (Andy) Kleehammer, and Robert (Jennifer) Koss, along with numerous nieces, nephews, and great-nieces and nephews.

She was preceded in death by her parents, John and Shirley Koss, and her son, Timothy O'Sullivan.

As a former nurse, Kathy dedicated her life to caring for others. Her compassion and nurturing spirit left a lasting impression on all who knew her.

A memorial service will be held at a later date. In lieu of flowers, donations may be made in her honor to NAMI or WINGS Program.
