McKayla Stoneback was the first On-site specialist for O2X. She started with O2X in 2019 as the On-Site Specialist for Frederick County Fire and Rescue Services in Frederick, Maryland. She has worked with the tactical population for over eight years now, implementing annual movement screenings, pre-habilitation programs, tactical strength and conditioning programs, and developing an overall health and wellness program for career fire departments. Since then, she has relocated to the Midwest and continues to work with O2X HQ in a new role.

McKayla graduated with a B.S. Exercise Science and a minor in Nutrition. Her experience in human performance started on the athletic side, working with athletes of all ages and ability levels. From there, she wanted to expand her experience and knowledge in the human performance field and became involved with the tactical side of human performance. Kayla then went back to continue her education and graduated with a Masters of Science in Kinesiology and Outdoor Recreation: Sports Performance & Conditioning from Southern Utah University. She chose to complete her Master thesis research within the tactical population. Her research was focused on identifying the significance of the relationship between the physical demands of firefighting and the physical fitness qualities of firefighters. Her research was then published. In addition, McKayla is also a certified Pregnancy & Postpartum Corrective Exercise Specialist and Athleticism Coach.

Outside of work you will find Kayla spending time with her family and friends, enjoying the outdoors, and making many firehouse visits to see her husband who is a career firefighter for Saint Paul Fire Dept. They enjoy working out together and staying active. Kayla enjoys fishing, camping, hiking, hunting, and staying active with her husband and 2 young kids.
