About
Stanley Nganga is the founder of Rx Fuel Nutrition, a certified Precision Nutrition coach, CrossFit Level 1 Trainer, and the exclusive nutrition coach at CrossFit Rowlett, where he also coaches athletes daily. A proud U.S. military veteran, kidney transplant recipient, and devoted husband and father of two, Stanley brings a unique perspective to health and performance coaching.
As an avid Crossfitter for over 15 years and a dedicated coach, fitness has been a cornerstone of Stanley’s life. His years on the floor, training, competing, and coaching, give him a deep understanding of the challenges athletes face and the mindset required to achieve sustainable results. Coaching isn’t just his profession, it’s his passion, and he thrives on helping clients translate nutrition and training into real progress.
His life experiences have shaped his approach to fitness and nutrition. Military service instilled discipline, resilience, and the ability to perform under pressure, while his kidney transplant gave him a profound appreciation for sustainable health and the challenges of rebuilding strength and energy. This combination allows him to genuinely connect with clients, whether they are busy parents reclaiming their energy, athletes striving for peak performance, or individuals determined to take control of their health after setbacks.
Through Rx Fuel Nutrition, Stanley combines science-backed methods with real-world experience. He leverages data-driven tools and personalized nutrition strategies to help clients fuel smarter, recover faster, and perform their best—both in the gym and in everyday life.
