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.

After receiving his Bachelors in Psychology from UT Dallas, Steve’s aspirations to help others led him to pursue a path in Physical Therapy. During his studies and hours spent volunteering, he began personal training and fell in love with the process of helping individuals grow stronger, more resilient, and overcome challenges in which they thought were impossible. A year later he decided to pursue after his passions of coaching and personal training. He has accumulated over 2,000 hours of individual/group training sessions and is eager to continue to learn as much as he can to help others achieve their fitness and health goals.

Jeff Brinkman


Jeff was born and raised in Northern Kentucky. He discovered Crossfit in 2012 after signing up for a GORUCK Challenge.

After relocating to Texas with his young family he quickly joined Crossfit Wylie (as one of our earliest members). His passion to learn and then teach quickly led to him becoming one of our first coaches. By 2013 the Olympic Weightlifting bug had fully taken hold, and that has been his focus ever since. Jeff continued coaching Crossfit classes and Weightlifting classes/seminars with Crossfit Wylie up until May 2019.

Later that same Jeff (along with Robert Hernandez) opened a weightlifting gym allowing them to focus on growing the sport of weightlifting by making it accessible to as many people as possible.

In April of 2021 Anchored & Risen Barbell club moved from its home in Plano to Crossfit Wylie bringing Jeff back to Crossfit Wylie as well.

He brings years of weightlifting coaching experience to our community, and is excited to grow the sport of weightlifting with us at Crossfit Wylie
