When not at home, he has resided in Chula Vista, California at the U.S. Olympic Training Center since 2006 to develop his archery skills.

[5] Kaminski started his archery career at the age of six near his hometown of Elma, New York, focusing on compound shooting at a Junior Olympic Development Club.

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.
