CrossFit Wylie is home to the area’s most experienced coaches. 

Kelly McKinney

Owner / Coach

Kelly has had a lifelong passion for health and fitness.  She has a degree in Psychology from Baylor University, is a certified nutrition coach, and is a CrossFit Level 1 Trainer.  After spending 20 years in the big corporate gyms and being bored with the workouts and not seeing the results she wanted, she decided to try CrossFit.  She instantly fell in love with the programming and community.  Wanting to provide the CrossFit methodology in such a fun and supportive environment is what led her into gym ownership.  She thrives on helping and seeing others improve and witnessing the bonds that are created here at CrossFit Wylie.
