By the age of 15, he focused his attention on recurve archery so he could one day compete in the Olympics.
At the 2016 Summer Olympics, he once again competed for the United States in the Men's team event and took home another silver Olympic medal, alongside teammates Brady Ellison and Zach Garrett.
