stefanie gilbreath


Stefanie is a University of Southern California graduate with a degree in human performance, having played women’s college basketball at both USC and New Mexico State University. She went on to play professional basketball for two years in Portugal and Germany. After spending her off-seasons in advertising at Gilbreath Communications Inc., Stefanie took on a full-time position as director of social media marketing and accounting at Gilbreath. In pursuit of another passion, Stefanie joined forces with her sister, Briana, to launch Power Portions, a healthy meal prep company developing nutritional meals for the athletic community as well as the general public. With her experience in business, accounting and athletics, Stefanie brings an excellent multi-faceted dynamic to Power Portions.

She has maintained a dedication to community service dating back to her college years, having been a volunteer for organizations such as the Boys and Girls Club of Santa Monica (as a nutrition leader), Sports Buddies (Jewish Boys and Girls Club of Glendale), Elementary School Girls Basketball Camps in Lousada, Portugal, Feeding America, Save the Children and Ascent Humanity Outreach, among many others. Along with her dedication to healthy meal prep, Stefanie believes her faith has led her to serve children struggling with obesity and applies her experience in this area into Power Portions’ efforts to give back to society.


nutrition for athletes

With backgrounds as professional athletes, we wanted to serve the athletic community by developing a company that would provide athletes with the food they like and the specificity they need. Each athlete is different, but within that uniqueness, athletes need and deserve clean and high-quality meals to fuel them no matter which season they are in. Having competed at the highest levels of sports for years, we are well-versed on what it takes to perform at an optimal level — and nutrition is a decisive factor.

client love


“I met with Power Portions two separate times when I was doing the LJ Performance challenges to get my healthy lifestyle back on track. They are so kind and helpful! Their meal plan was specific to my needs and helped me get back on track and to a healthy lifestyle. I loved the plan because it included normal healthy foods — it didn’t feel like I was starving myself. Their plan for me helped me long-term and I’ve been able to maintain it long-term — which is so valuable! Thank you Power Portions — y’all rock!”


They were so helpful and informative!! Highly recommend if you’re looking for some help navigating your journey with balanced eating & healthy practices.


Mrs. Butler is extremely professional and very knowledgeable. I really enjoyed speaking with her and gaining more information than I thought I would get. You can hear her passion in what she does. She put my husband and I on a program that works for us at our age. I would recommend her to anyone interested in living a healthier life!
