Katherine Psaros – Of Rockland, passed away peacefully surrounded by her family on June 17, 2026 at 86 years old.

Born and raised in Somerville, MA, Katherine was the beloved daughter of the late Nicholas George and Anna (Saricostas) Kacoyanis.

Lovingly known as Kay, she was an excellent cook and left behind a recipe book the size of an encyclopedia. She was a skillful cribbage player, took great joy in winning card games, and was a savvy crossword solver. A sweet tooth by nature, she took great care making sure every box of chocolate was thoroughly enjoyed. In addition to the occasional chocolate delight, she also enjoyed cranking a few slots at the casino as a treat.

Kay loved sharing Greek family traditions with her loved ones, including rolling grape leaves and making Greek cookies. With her sharp wit, she had an ability to crack a joke at the perfect moment. She was a fierce, selfless presence in her family’s lives, always centering them and making anyone who walked through the door feel at home. She will be greatly missed.

Cherished wife of George Psaros. Devoted mother of Jennifer Calder and her husband Greg, Stephen Psaros and his wife Candace, and Gregory Psaros. Beloved sister of Mary Fries, Christine Sillari and her late husband John, Georgia Woodsworth, and the late George Kacoyanis.

Known to many as Yiayia, she leaves behind her treasured grandchildren, Olivia Calder and her husband Christopher Young, Sophia Calder, Jillian Psaros, Katelyn Psaros, and Jack Psaros. She also leaves behind many dear nieces and nephews.
