Jon-David Thurston Gleason, 42, passed away Wednesday, Aug. 5, 2020, from an automobile accident. He was born in Rockport Jan. 9, 1978. He graduated from Camden High School in 1996.

In 2010, Jon married the love of his life, Teresa Lynn Witherly. Their marriage began with three stepchildren, Kyle, Connor and Sarah, followed a year later by their daughter, Ava. Together they formed the “perfect union,” in Union.

Jon is survived by his forever wife, Teresa (Witherly) Gleason of Union; children Kyle Williams of Belfast, Connor Williams, Sarah Williams and Ava Gleason, all of Union. Jon also leaves behind a most cherished and influential grandmother, “Mammie,” Rosalie Gleason of Appleton, who had a tremendous influence in his life; father Craig Thurston Gleason and wife Gail of Union; and mother Sybil (Clement) Wentworth and husband, Joel, of Union; sisters Nicole Glidden and her husband, Shawn, and their daughter, Kelsey, of North Yarmouth, Carrie Gleason and fiancé Gerry of Hanover; as well many beloved aunts, uncles, cousins and six step-siblings; brokenhearted in-laws Galen and Barbara Witherly of Hermon.

He was predeceased by his paternal grandfather, "Pop" William Thurston Gleason, who was the family patriarch and Jon’s lifetime mentor; maternal grandparents Carl and Frances (Jones) Clement; two maternal uncles Tom and Bill Clement.

Jon-David attended Union Elementary, Middle and High School in MSAD 40. He spent some of his high school years attending Carrabassett Valley Academy near Sugarloaf, where he participated in the free-style and mogul skiing competitions.

His high school years were interrupted when he was critically injured in a car accident in his junior year. This very serious brain injury required much determination and hard work, which he very diligently put in and proudly graduated from Camden-Rockport in 1996. He would often stop in and visit some of the wonderful medical professionals at Maine Medical Center and New England Rehabilitation Hospital to thank them.

Jon-David went on to become an avid skydiver, ski patroller and instructor. He grew up involved in his father’s drag racing circuit and was considered a vital member of the team at an early age. He later became a professional truck driver and will be sadly missed by his coworkers at Performance Food Group. Of all the accomplishments he achieved, he was most proud of his role as a husband and father.

Jon-David was deeply loved by many, and he will be sadly missed by his loving family, many friends and his four-legged partner, Summer (Happy Dog 213). We are proud to say we knew him and loved him. He will certainly be watching over us. Good night, my sweet.

Visiting hours will be held Friday, Aug. 14, from 4 to 6 p.m. at Riposta Funeral Home, 182 Waldo Ave., Belfast. A graveside service will follow Aug. 15 at 10 a.m. at Pine Grove Cemetery in Appleton. Those who wish may make memorial contributions to Jon-David T. Gleason Children’s Educational Fund Camden National Bank, 52 Burkett Road, Union, ME 04862.
