John Robert "Jack" “Jackie” Siebert, 88, of Noblesville, Indiana, passed away on Tuesday, February 24, 2026. He was born on December 3, 1937 to the late William and Margaret (Foster) Siebert in North Bergen, New Jersey.

Jack grew up in Jersey City, NJ, attended St. Aloysius Academy and graduated from Teaneck High School in Teaneck, NJ. He was the 3rd generation owner of Siebert Trucking Company, and later opened Spindrift Limousine from 1985-2004. Jack always had a strong work ethic he got from his father that he passed onto his son.

Jack met his wife, Donna, on a blind date set up by his best friend's wife. For 30 years, they raised their family in Little Silver, NJ, and in 2009 moved to Noblesville, IN to be closer to his granddaughters.

Jack loved spending summers in Sea Bright at the Jersey Shore, where he enjoyed his friend group who named themselves The “Farkles.” He loved Boxer dogs, boating, Lionel trains, and cars, especially his first car, a 1955 yellow Ford Thunderbird. Jack also loved collecting records and listening to his favorite music like Pat Boone, Frank Sinatra, Dean Martin, as well as his parents' favorite music. Most of all, Jack loved his family and being D-Dad to his granddaughters who adored him. Jack always said with a big smile, "We have the best family."

He is survived by his wife of 54 years, Donna Siebert; son, John “Jay” Siebert; daughter, Jessica (Keith) Clock; 3 granddaughters, Lillian, Allison and Amelia Clock; and Mary Foster Schoales, his cousin who grew up with him like a sister.
