Mariah Schmitt

USAG Girls' Team Coach

USAG Girls' Team Coach


I was born and raised in Kansas where I competed in gymnastics for 17 years up through Level 10.  I received a full scholarship to compete at NC State after high school, but decided to transition to coaching instead after my freshman year. I love to incorporate fun and challenging games into practice to help keep things interesting, and I love to be silly with the girls! My years of training and competing in gymnastics in an environment that was like my second home have inspired me to help each young gymnast to truly believe in herself so she is able to reach her full potential. When I am not coaching, I love to draw and spend time with my two dogs, Blu and Bonnie. I just had my first child too, her name is Charlie!

​​​​​​​Amanda grew up in Wake Forest, graduating Wake Forest-Rolesville High School.  She then graduated from UNC Wilmington with a major in Exercise Physiology and a minor in Athletic Recreation. She was a Personal Athletic Trainer for 15+ years and worked at Rex Wellness Center-Cardiac Rehab for 10 years prior to coming to Tri-County 8 years ago. She is the proud mother of 4 kids, two of which are on our Girls' Competitive team.  She has enjoyed homeschooling her kids for 11 years.  In her free time she enjoys running, yoga, Tae Kwon Doe, weight training, dance, tennis and of course doing gymnastics.
