Trami Thi

Trami started CrossFit to build confidence, relieve stress, and to live a healthier lifestyle.

Trami was always passionate about fitness.

She participated in competitive sports since elementary school.

She ran on the track and field team in 4th and 5th grade. She played soccer and ran cross country in high school. She received her first degree black belt in Tae Kwon Do, where she sparred in competitions.

At the peak of the sports season senior year, an ACL and meniscus injury put her on crutches for over 8 months. She felt broken, discouraged, and wanted to give up on fitness. She watched her teammates on the sidelines. She felt like her body had let her down.

She began put her health and fitness last. She adapted terrible eating habits. In college, she gained weight, and felt tired all the time. She really was letting herself go…

One day, when she came home to visit her parents, her mom thought she was pregnant! Well… she wasn’t!

That was the last straw.

She decided to try CrossFit. She fell in love with the community of people and the competitive atmosphere.

She found friends that always pushed and encouraged her to be better. She learned to view nutrition as a way to fuel herself. CrossFit was an amazing stress reliever, and she felt better than she ever had before! Her abs were showing for the first time! She was hooked!

She has since wanted to share her passion for fitness with others.

She worked to get her CrossFit Level 1 Certificate.

She loves coaching because it helps people unleash the hidden power within themselves. The victories that people achieve during class carry into their every day life.

Liz Cromwell
Liz Cromwell

Liz first started CrossFit in November of 2013 after returning from living in Guatemala for 6 years.

She wanted to find something more than just running and missed the atmosphere of competitive athletics. Growing up playing sports, athletics was always part of her life but once she was out of college, the team aspect of athletics dwindled. And that’s when she found CrossFit. Since starting CrossFit, she has enjoyed the community of people, the competitive atmosphere and living a healthier lifestyle. Her passion for education and community lead her to coaching and she hopes to share this with everyone who walks in the gym.

Nathaniel Siems
Nathaniel Siems

Nathaniel played for Stillwater Oklahoma Trinity Homeschool basketball team in high school…

…and won the 5A national championship his sophomore year and 5A runner-up the following year.  He played various intramural sports during his time at Southern Nazarene University.

Despite his competitive background, Nathaniel did not have much experience in weight training and when he graduated from SNU he decided to change that. Nathaniel heard about CrossFit from a friend and after trying it he was instantly hooked. After a short time of doing CrossFit he noticed major changes in his strength and endurance and became interested in the coaching aspect of CrossFit.

Nathaniel’s favorite moments in coaching CrossFit are when someone sets a goal that seems impossible to them, and after hard work and dedication they reach that goal.
