Diane Monique Parenteau, age 75, of Derby Line, Vermont, passed away unexpectedly on October 3rd, 2025, in Derby Line. She was born on April 5th, 1950, in Derby, Vermont to Theotime and Cecile Fortier Parenteau.

Diane was a beloved daughter, sister, and aunt whose greatest joy in life was her family. She cherished time spent with loved ones, whether visiting her brother Michel in New York City or gathering with extended family in Canada. She especially loved when her nieces and nephews came to stay overnight playing games, baking treats, and tending the garden together.

Halloween was one of Diane's favorite times of year, as she delighted in seeing neighborhood children dressed in costume and handing out special snack bags of candy. She was known for her kind, generous spirit and her willingness to help anyone in need. Her faith was a central part of her life; she lived each day with devotion to her family and to God, attending Mass faithfully at Saint Edward's Catholic Church in Derby Line.

Diane worked as an accountant for Marcel Roberts Real Estate and the Cow Palace for years. Where she met lifelong friends, Lori Roberts and Missy Nelson.

She was diagnosed with Parkinson's Disease, a condition she faced with strength and grace until the end of her life.

She is survived by her brother Yvan Parenteau and his wife Linda (Carter) of Newport, Vermont; her sister Helene (Parenteau) and her husband Richard Sykes of Newport, Vermont; and by her beloved nieces and nephews: Yvan Parenteau Jr. and his wife Amanda and family of Newport, Vermont; Heather Parenteau and her partner John Smith and family of Edgewood, Maryland; Daryk Sykes and his partner Krista Perkins and family of Westmore, Vermont; and Leslie (Sykes) and her husband Jeremy Delabruere and family of Newport, Vermont. She also leaves behind several great-nieces and great-nephews who will always remember her warmth and kindness.

Diane was predeceased by her parents, Theotime and Cecile Parenteau, and her brother Michel Parenteau.

Family and friends are invited to attend her Christian Burial at Saint Edward's Cemetery. Located on Elm Street, October 25th at 11:00 AM.
