Hi! My name is Nini Nguyen. I am from Fairview, Oregon and I moved to Monmouth for college. I have earned my exercise science degree from Western Oregon University in 2022 and shortly after, was selected for an Outstanding Student Award in the Exercise Science Division. I am an Olympic-style weightlifter and CrossFit coach. I have taught a variety of group classes at Monmouth Fitness, coached CrossFit Kids and a team of girls’ basketball. My aspiration is to help people achieve their goals in strength and conditioning. When I am not lifting or coaching, I like to cook, read, and take long walks.
