Jack Brian Polonsky began changing this world for the better on February 15, 2010, in Burlington, IA, the cherished son of Jason and Kristi Edwards Polonsky. He was a vital part of a loving family that celebrated time spent together. During his life he was blessed to enjoy, travel, adventure, and quality time with family and friends.
Jack was a soon to be sophomore at Fairfield High School who was active with the Fairfield Student Council, Future Business Leaders of America, choir, and cross country. By far his favorite part about school was the opportunity to be social and interact with friends and teachers.
Jack was an avid Detroit Lions Fan and had a wide range of musical taste. He was never afraid to strike up a conversation with friends or even someone new, whether it was out of curiosity or just to be friendly. Jack never missed an opportunity to discuss sports with his brother, Cooper, and seldom was at home without his four-legged friend, Enzo by his side. When there was time between activities he would play video games with friends, collect Pokémon cards, and challenge anyone to a hand of UNO. He also wasn’t afraid to admit he was a proud Star Wars nerd.
When Jack was dealt a challenging hand in life with the diagnosis of T-cell Lymphoma, he met the challenge with poise and determination that showed his strength and love for life and his family. He was surrounded by his family, his community and a medical team that was always impressed by his quick, easy smile even in the face of adversity. Jack road the highs and lows of his journey, never feeling sorry for himself and always doing his best to lift others. He refused to let cancer define him as he continued to live his life, plan his next adventure, and enjoy his favorite people and pastimes.
Spending time with family was always his top priority and a great source of happiness. The numerous trips together created lasting memories of love and laughter spanning everything from the beach to the mountains, and numerous beautiful sunsets. He lit up every room he entered, everyone he met was a new friend, and they all experienced his smile.
Jack Polonsky fought the good fight, showing his family, his friends, and his community what it is like to face adversity, but move forward and live life to the fullest. As we say goodbye, we remember his smile, the times we shared with him, and the memories that were made along the way.
