JACK'S STORY


The Smile Like Jack Memorial Fund was established in memory of Jack William O’Brien, a loving son and brother, caring friend, and hard working young man that touched the lives of many with his contagious smile. Jack tragically passed away in a snowmobile accident on March 3rd, 2022. In his 20 short years, he had accomplished many things and leaves behind a legacy that is in a caliber of its own. Jack lived life to the fullest. He was always working exceptionally hard to accomplish his set of goals while also living the outdoorsman lifestyle: fishing, hunting, and riding. Our goal is that the Smile Like Jack Memorial Fund will bring other individuals (with similar passions) the opportunity to live their legacy just as Jack would - working immensely hard in the trades and living life to the fullest in the great outdoors.
