Justin grew up in Cicero, IN, and was a graduate of Hamilton Heights High School, attending classes at Purdue in West Lafayette after high school.
Justin's childhood was filled with memorable experiences surrounded by family and friends – long summer weekends exploring state parks with his parents and sister, camping trips with numerous other families and children, the tradition of Christmas holidays spent at Pokagon State Park with his extended family, and spring breaks on Florida beaches. He spent many hours during his teen years with his tribe of friends hanging out and playing video games. He also loved spending time playing with the family dogs, Domino and Ellie.
Justin was an active young man who played soccer all through his school years, which culminated in helping his Huskies team win their first sectional title in his senior year. He enjoyed his lake time with family and friends and was also a natural at all things water sports from a young age. His adventurous nature also led him to activities like rock climbing and scuba diving. People who knew Justin knew he loved skateboarding – taking it up at a young age, continuing it through multiple injuries and into adulthood – sometimes traveling long distances to experience skateparks and getting to know the people who frequented them.
Justin was an independent spirit and intensely curious, always taking on unique hobbies without regard to social conventions or what was trending with his peers. His interests were varied but the one that endured from his childhood to his adult life was inspired by his Grandma Jo in the kitchen. He loved to experiment with food, using his intuition and creativity for all things delicious and interesting. He applied his culinary talent to working at restaurants as an adult, and his compassionate nature inspired him to cook and serve food to the homeless. Some of his happiest moments were spent using his skills on the family's Big Green Egg and the Blackstone Grill with his dad.
Justin faced many challenges throughout his adult life, yet he endured them with incredible courage and remained a person of remarkable kindness and sincerity. Those closest to him were touched by his gentle spirit and unwavering goodness. His memory will be cherished by his family, friends, and all who were fortunate enough to know him.
