The big day may have come and gone, but De'Tuan is here to stay!
At Sigma Wellness & Performance Medicine, we see exercise and nutrition as more than boxes to check—they’re powerful levers to transform how you feel, think, move, and age. Our Exercise & Nutritional Coaching is built around the belief that true “fitness” isn’t about perfection or punishment. It’s about building a body that works for your life: strong enough, resilient enough, and energized enough to carry you through the things that matter most.
This is where our philosophy comes to life:
Shaping Strength. Sustaining Wellness. Striving for Optimal Performance.
Strength isn’t just about heavy weights or PRs in the gym. It’s the capacity to carry your kids up the stairs without thinking about it, to hike with friends, to recover from stress, to stay independent as you age.
Our coaching focuses on practical, functional strength:
We’re not here to change you into someone else. We’re here to shape the strongest version of you.
Fad diets and extreme programs may give short-term results, but they rarely give you health. At Sigma, we focus on sustainable nutrition that supports your hormones, metabolism, gut health, and longevity—not just the number on the scale.
Our Nutritional Coaching weaves together:
Wellness isn’t a 30-day challenge. It’s a way of living that you can maintain for the long haul.
“Performance” doesn’t just belong to athletes. It belongs to anyone who wants to show up fully in their life—whether that’s leading a team, running a household, excelling in sport, or simply feeling sharp, calm, and capable day to day.
With Exercise & Nutritional Coaching at Sigma, we aim to help you:
Our coaching integrates seamlessly with our broader services—hormone optimization, peptide therapy, and functional lab analysis—so your plan is not generic. It’s precision-built for your body, your goals, and your season of life.

De'Tuan Williams, MSA
I’m a former Division I football player at the University of Northern Colorado, originally from Denver and now based in Dallas, Texas. I hold a Bachelor’s degree in Sports & Exercise Science with an emphasis in Coaching, as well as a Master’s in Sports Administration. Before stepping into leadership, fitness programming, and acting, I spent years as a football and track coach, helping young athletes become the best versions of themselves, on and off the field.
I’m also a proud father to a beautiful daughter, a son, a brother, a mentor, a coach, an actor, a sales leader, a friend, and above all, a follower of Christ.
My passion for helping people move, feel, and live better started early. In 2019, I began creating personalized fitness and nutrition programs for men and women of all ages. One of my early clients was a 50-year-old man dealing with chronic pain in his ankles; after six weeks, his strength and mobility improved so dramatically that his doctor began referring patients directly to me. That’s when I knew this calling was bigger than reps and meal plans.
I believe in keeping fitness real, no gimmicks, no extremes, just progress you can build your life on. Everything I do is driven by purpose, discipline, and faith. Whether I’m coaching, leading a team, helping someone change their habits, or telling stories through acting, my journey has been built on growth, resilience, and the desire to make a positive impact wherever God places me.
