The Team

Who We Are


Katherine Robertson (Kat)

Owner and Head Coach

Hey! My name is Katherine Robertson.  I bought

Gymnastics Unlimited from Tina Hand in 2018. We have

been on a wild ride ever since.  I oversee all the business

aspects at GU along with being a Head Coach. 

We are ever changing, ever evolving, and are always looking toward the future to see what else GU can offer the community.   I love working with the kiddos and giving them a home away from home!


Marissa Moss

Head Coach

Hi there.  I am Marissa Moss. Graham has been my

home pretty much my whole life.  My time at

Gymnastics Unlimited started when  I was

10 years old.  I begged my mom to put me in gymnastics.

When she finally gave in, Tina would have to

turn the lights out to get me to leave.

I loved it then and I love it now. 


What I enjoy the most is sharing my love and

knowledge of the sport with the younger kids.  There is

nothing like seeing the excitement in a kids eye

the first time they get their

back-handspring or front tuck!!


Coach Mo

Jr Coach
Recreational Gymnastics, Tumbling, and Team

Hi there.  My name is Mo, but most people call me Mo. I am a Senior and a Varsity  Cheerleader at Graham ISD.   I plan to attend Tarleton University next fall. 

I have worked for Kat since 2020, but my time at GU started when I was 6 years old.   I have loved flipping and tumbling for as long as I can remember.


I teach Rec classes and help out with team occasionally, but especially love the Tumbling class.  I like being apart of the next generation of cheerleaders learning their flips and tricks.

Coach Rylee

Jr. Coach

Team, Recreational Gymnastics, and Tumbling


Hello, I'm Rylee!!  I am a junior at Graham High School.  I am in Student Counsel, Drama Club, and I am a varsity cheerleader.  I also do competitive cheer in Wichita Falls.

I have be at GU for about a year, but before that I coached at Ignite Academy.

I love coaching because I get to watch the gymnasts learn new skills and have fun doing it.

Kendra Irby

Bungee Instructor

Hey Ya'll. My name is Kendra Irby & I have called

Graham home for most of my life. I am a mom 

of 4 who just loves to have fun!

Bungee has become a great place for me to make

connections & get in a

great workout at the same time.

 I absolutely LOVE the family atmosphere here

at Gymnastics Unlimited!



Kelly Westbrook

The Person

Hey!! I'm Kelly.  I know you can't tell, but I am Kat's sister. 


I am a recent transplant to Graham and I think this town is absolutely beautiful.  I have been at GU for almost a year. I am at the gym everyday.  I am the fixer of whatever is broken (yes I probably broke it), the maker of the best team snacks, the coach's kids sitter, the fill-in for whoever/whenever, and everything in between. 

Basically, I just do what needs to be done and a little bit of what Kat tells me too (just don't tell her I don't do everything she tells me!!!)

I am learning more about gymnastics with each class and truly enjoy it.  I am happy to be a part of my sister dream and am excited for everything we are planning for the future. 

Come see us!! You won't be disappointed!
