The Lifestyle Queen

Trustworthy, Trailblazer, teammate

Heeey!! I’m Stefanie, a Texas native, retired professional basketball player, and CEO of Power Portions and The GNAW Collective. 

I have intimate experience lacing up my sneakers and navigating the challenges you face today; uncovering the right way to fuel your performance in a way that feels doable, finding sisterhood in a community of color that understands our unique, but very real challenges, and evaluating who is offering nutrition recommendations, menu plans and supplement recommendations you can trust. As a woman who struggled with conflicted opinions about my body image and fluctuating weight, I can vulnerably share that it’s taken me a while to find my way in the world of nutrition. But these days?  I’ve finally reached the perfect balance of merging my love of sports with a passion for helping others find their own personal fitness and nutrition solutions.

I’m a strong advocate for having a balanced life and taking accountability for your personal actions. That’s why you will often hear me talk about self-care, getting organized, and taking the necessary…

steps to make sure you do what is best for your long-term personal health and happiness. 

Outside of work (because we DO believe in balance and walking the walk), you’ll find me volunteering, hanging out with my family and friends, shooting some type of content, shopping for my next pair of sneakers (you can’t have too many, right?) and loving on my niece and nephew. 

A true Texas girl

Passionate, driven, professional

Hey ya’ll! I’m Bri! Registered dietitian and co-founder of Power Portions and The GNAW Collective. I am a registered dietitian by training, but my love for good food dates back to childhood; my mouth waters when I think about my granny putting a hot southern meal on the table every day.

As the lead dietitian, I am passionate about helping pro athletes, and active women of color across the country feel their best and enjoy food while doing it. I’m here to change your assumption that you have to choose eating your cultural foods OR fueling your best practices and performance; I promise you can do both.

But, as much as I love what I do, what holds my heart is my FAMILY and my faith! I’m a wife and mommy of two kiddos, and I truly believe my purpose on this earth is to serve and enjoy some Blue Bell ice cream and a good book while doing so!
