Kristin Tucker
Owner/CrossFit Coach

Kristin is a mother of 2, former collegiate volleyball player, 2015 CrossFit Games athlete, and has 15 years of experience in sports medicine.

Kristin found CrossFit as a way to regain her health after starting a family, and found a passion for helping others take back their lives. She is an expert at modifying exercise to meet any skill level! Paired with her Athletic Training background, she is a wealth of knowledge of health, fitness, and injury prevention.


Ryan Doss DC

Dr. Doss is co-owner of CrossFit Lubbock, he has 2 wonderful girls with his wife Masey, they are active in their church Calvary Baptist and enjoy helping people realize just how capable they are. Growing up he was active in multiple sports, ultimately settling on tennis and playing at New Mexico State University. This background drove him to love the field of athletics, health, and wellness. Unfortunately, with Chiropractic school, business, and everyday life he found himself sitting at 310 pounds.
With the help of a great group of coaches, friends, and nutrition counseling, he has successfully lost 100 pounds, attained his CF-L1, and gained an appreciation for what CrossFit can do for the inactive or sick population looking for a change. His goal is to help you break through the mental and physical barriers that stand in the way of your success story! Let’s Get Started!

CrossFit Coach

I am a Presidential Fellow and Ph.D. student at Texas Tech University. I am also a former professional actor with The American Shakespeare Center. I have been CrossFitting since 2011 and have won numerous competitions. The highlight of my career has been competing on the 2018 CFLBK Regionals Team. I hold a CFL1 and a CrossFit Kettlebell certification. I hope to qualify for the CrossFit Games as a 35-39 Masters athlete. I coach classes regularly and I am also available for personal training. Competing is fun, but for me, nothing beats coaching at CFLBK alongside Tim, Abby, Kristin, and Dr. Doss! No matter your goal, no matter your experience, I want to make your time at CFLBK the best part of your day! Let's go!
