Welcome, my name is Brigitt Castille. I am a mother of two and married to my high school sweetheart. I grew up in Dallas, Texas but I now call Phoenix, Arizona home.

I am a former competitive swimmer, which helped make exercise a part of my lifestyle as I moved into adulthood. I began teaching group fitness classes ten years ago and becoming a personal trainer was a natural progression. What I didn’t see coming was my passion for nutrition. A random email that appeared in my inbox had a short series of nutrition videos. I was completely hooked.

I turned my focus to nutrition and pursued my first certification. I couldn’t get enough of it. I quickly realized that I could help people on a deeper level when working on their nutrition. It is so much more complex than people realize and can be more important than exercise.

While I love personal training and being a group fitness influencer, my reach for changing lives is greater with nutrition coaching. In 2016, I moved my coaching business online. It has exceeded my expectations in being more effective for my clients’ success. The great thing is, I’m still able to connect with them but deliver so much more. Check out my transformation story >>

The Yin-Yang symbol in my logo is no coincidence. I believe in living a balanced life and I implement this philosophy in my coaching approach. I want to teach my clients that they can still eat all the foods they love because, food is not the enemy. Unlocking the “Whys” surrounding the behavior relating to food is the key. This is where lives are forever changed.

What makes me different?


noun:    strong and barely controllable emotion /                an intense desire or enthusiasm for something.

I realized my passion for coaching in my late teens as a swim coach. I saw I could teach in a way that was easy to understand, motivating and effective. I’ve always had a drive to set and achieve goals, even in the face of adversity. For as long as I can remember, if I ever felt I had information that could help someone, I couldn’t resist sharing it. Years later, it’s now crystal clear that coaching clients is my true passion and purpose.
