I created Unlock to provide the most honest, educated, and experienced exercise & nutrition services in the Dallas Area. If I can’t help you, I will direct you to someone who can. Having my hand in the DFW fitness scene for so many years has given me the advantage of knowing the best in the field. Call me directly to learn how Unlock can help you.

My Method is centered around all aspects of balanced wellbeing in your life – nutrition, mental/emotional wellness, and fitness. You’ll learn to listen to your body and explore what foods & biomechanics work best for you!


My life motto: Behave Blessed!
