About Brandon

My name is Brandon Osorio, Owner and Founder of Black Diamond Fitness LLC.

Born in Las Vegas, Nevada, I grew up facing challenges that no child should have to endure. My childhood was shaped by exposure to substance abuse, unhealthy family dynamics, and sexual abuse. Those experiences taught me difficult lessons at a young age, but they also sparked something within me—a desire to become a protector and a source of strength for others.

That calling led me to serve my country as an Infantryman in the United States Army. For the first time in my life, I felt like I was living my purpose. Service gave me direction, discipline, and the opportunity to be part of something greater than myself.

Unfortunately, my journey took an unexpected turn when a workplace accident left me with a broken back and severe nerve damage. The injuries changed my life forever. The physical pain was overwhelming, but the mental battle that followed was even greater. Depression, anxiety, and suicidal thoughts became daily struggles. There were moments when giving up seemed easier than moving forward.

What kept me going were my two sons.

They became my reason to fight. My reason to heal. My reason to keep taking one step forward, even when the future seemed impossible to imagine.

Today, I am blessed with a happy marriage, healthy children, and a quality of life that I once believed was beyond reach. While I still face physical limitations, I have rebuilt my health, my mindset, and my purpose. I have experienced firsthand what it means to lose both your body and your identity—and what it takes to reclaim them.

That journey is what inspired Black Diamond Fitness.

Through health, fitness, and personal development, I now have the privilege of serving others once again. My mission is not simply to help people lose weight, gain muscle, or improve performance. It is to help them discover the strength they already possess. To help them push beyond perceived limits. To show them that adversity does not have to define their future.

My experiences with substance abuse, poor parenting, depression, anxiety, suicidal ideation, loss, and recovery have given me a unique perspective that I bring to every client relationship. I understand what it feels like to struggle. I understand what it feels like to feel lost. And I understand what it takes to rebuild.

At Black Diamond Fitness, we believe that your past does not determine your future. No matter what challenges you face, there is always an opportunity to grow stronger, rise higher, and discover your true potential.

Because sometimes the strongest people are not the ones who have avoided hardship—they are the ones who have overcome it.
