Sean E. Flaherty age 57, of Braintree, died peacefully, Sunday, November 8, 2026 at Brigham and Women’s Hospital in Boston, after a brave battle with cancer, with his loving wife by his side.

Sean was born in Boston. He was a graduate of Southeastern Regional Vocational Technical High School, Class of 1986. He earned his Bachelor’s degree from Bridgewater State University.

Sean loved technology all his life and turned that passion into a long career in Information Technology. He was the first in line to get a new gadget, and the person family and friends called when something wouldn’t connect, load, or turn on. He was always glad to help.

Sean was a beer connoisseur and loved visiting breweries across New England. He was happiest when cooking for family gatherings and filling the house with good food. Anyone who spent time with Sean knew his fun, quirky sense of humor; he could always make a room laugh. Above all, he was a loving husband, father, son, brother, brother-in-law, and uncle.

Beloved husband for twenty-eight years of Patricia A. “Patty” (McElaney) Flaherty.

Devoted father of Aidan R. Flaherty and Rory L. Flaherty.

Son of Thomas Flaherty and his wife Mary of Agawam, Mary Anne (Sieberg) Slaney of Warwick, Rhode Island and her late husband Bernard W. Slaney.

Brother of Bernard A. Slaney and his partner Christina Goncalo of Taunton, Erin Flaherty of South Burlington, Vermont.

Sean is also survived by six nieces and nephews, one great nephew, many cousins, in-laws, and extended family members.

A celebration of Sean’s life will be held at a later date, with details to be announced.
