Issac Sellner, of Pittsburg, Pennsylvania, is running in Fort Worth, Texas to honor his brother, PVT Karl Sellner, who passed away in September 2016. “Karl was the kindest, most thoughtful, and loving brother, son, and husband. He was always trying to cheer people up and make them laugh.” Issac fondly remembers how hard his brother was on him growing up - pushing him to be the best he could be. “When I set my mind to something, I’ll complete it because that’s what Karl would do.” Issac says that he has a difficult time pushing himself to heal on his own, is excited to have a team to rely on, and is ready to push himself mentally and physically.
