Katie Wilday

General Manager/Coach

Katie has been a part of the Dynamix Family since 2015 and says it was the best decision she's ever made. She received her CF-Level 1 certification shortly after joining the box and has never looked back. As a coach Katie's biggest reward is seeing the excited look on her members’ faces when they do something they never thought they could before. "If you are looking for a great gym you came to right place!" Catch coach Katie on instagram @katiekagefitness!

Maria Barklie


The only thing that Maria loves more than CrossFit is her Dynamix Family.  Since 2010 she has been a part of the constant evolution of CrossFit. She enjoys helping people find and develop their inner coach. Since mind and body are so intertwined, changing one leads to change in the other. By helping an athlete with fitness, we change their life. At Dynamix Maria strives to constantly be better and is inspired, hopes to inspire, is lifted and hopes to lift those around her. So if you’re ever at the box and hear a loud YEAAAHHH, she’s there.
