Owner & Program Director Jen Posten

Owner, Tecumseh Gymnastics Academy 2008-Present

THS Head Varsity Coach 2002-Present


My coaching philosophy is guided by the belief that children can learn the discipline of gymnastics in a fun, safe, and protective environment. The idea that success is different for every individual and it is my mission to guide each child to their own personal level of success and that athletes will achieve their full gymnastics potential with individualized development.

It is my belief that the sport of Gymnastics is a teaching tool for young gymnasts to learn the value of hard work, dedication, personal discipline, competition, teamwork, and character. We learn through experience. This provides the opportunity to learn through sport the qualities that carry over into real life. It gives them the chance to build bonds and form lifelong relationships that come from being a part of something bigger. It is my hope that I have helped prepare them to travel on to bigger and better things when they leave the gym.

As a coach it is my job to be a leader; both in the gym and out, but also to guide my athletes to be strong leaders themselves by involving them in their training plans, skill goals, and team bonding. I strive to find balance between empowering athletes with ownership over their goals and plans, while maintaining structure and discipline to ensure productivity in their gymnastics career.

Meet the Coaches...
Miss Lindsay has been coaching at TGA for 2 years "I was lucky enough to a member THS Gymnastics teams 02-04. I also loved choreographing my own routines and to this day...(almost 15 years later) I still remember my beam routine!" Miss Lindsay is the mommy to two amazing little people. Her son Ben is seven and loves everything boy, including karate, soccer, baseball and mud. Her daughter Olivia is four and takes classes at TGA as well as dance classes. Miss Lindsay owns her own photography business and have a small studio space in the beautiful downtown triangle of Dundee. Her background is in Child Development and working with younger kids has always been "her jam". "I love helping the little ones in my class overcome their fears whether it be getting up and walking on the beam alone or going upside down on the bars. To me there is nothing better than an excited little face when they can do it for the first time on their own."

Miss Kirsten has been coaching at TGA for 8 years." I started gymnastics at a young age and trained/competed in club gymnastics for about 10 years until high school. In 2005, I joined the Tecumseh High School team, and was a 4 year varsity gymnast until I graduated, and headed off to college, forcing me to hang my leotards up! My favorite events to coach are vault and beam."Gymnastics was a part of my life for as long as I can remember. When I could no longer compete, I had to find a way to stay involved in the sport that gave me so much, so I started coaching! It is one of my greatest joys in life being able to share my love of the sport with so many lives, and be the coach and mentor to my gymnasts that my coach was for me." Kirsten and her husband Marty share their home with their dog and cat.

Miss Brooke has been coaching at TGA for 6 years. "I did gymnastics for 7 years. I started on TGA’s Pre-Team and progressed through Xcel levels. I then was a Varsity gymnast for Tecumseh High School." Miss Brooke currently goes to school at Washtenaw Community College while coaching here at Tecumseh Gymnastics Academy.

Miss Jenna has been coaching at TGA for 7 years. "My interest in gymnastics began at a young age and continued to grow through middle school. I however switched to a different sport in high school until I realized that I would rather be back on the gymnastics team. I competed on The Varsity Team during my junior and senior year! " Jenna likes to spend her summers at Devils Lake with her family on their boat. "I coach a wide range of classes from Beginner 1 to Team. My favorite events to coach include beam and floor."

While Marcus was never a gymnast himself, he was raised in the gym. Currently a business student at Jackson College, Marcus is always at the desk to greet gymnasts and parents and always ready to handout the emergency bandaids and hair ties.
