Hayley C. McNeff, 37

Such a bright light has left this world too soon with the unexpected but peaceful passing of Hayley C. McNeff of Sudbury on August 8, 2025.

Born and raised in Acton, she was the beloved daughter of David J. McNeff of Wayland and Michelle C. Walker of South Dartmouth and was the cherished sister of Ashley S. McNeff of San Francisco and Scott P. McNeff of Quincy. She was the niece of Susan G. McNeff of Newburyport and Kathy M. McNeff of Needham.

Hayley graduated from Acton-Carlisle High School and the University of Massachusetts Amherst with a bachelor of arts degree. A lifelong athlete, she excelled as an accomplished equestrian, talented board diver, and skier as a youth and young adult. As an adult, she discovered a passion for bodybuilding and was a U.S. champion during her career. She later pursued graduate studies in psychology, driven by a desire to better understand and help others.

Hayley was known for her quick wit and constant sense of humor; she had a gift for making those around her laugh and feel welcomed. Her energy and determination were a constant in her life, and she always accomplished what she set out to achieve. She treasured her friendships and nurtured strong, lasting relationships with those who knew her best. Hayley will be deeply missed by her parents, siblings, extended family, and friends.

Visitation will be at the George F. Doherty & Sons Funeral Home, 477 Washington Street, Wellesley on Saturday, August 16, from 10-11 a.m. followed by a funeral service at 11 a.m. Relatives and friends are kindly invited.
