"It doesn't get easier, you just get better at it."


I’ve been a certified personal trainer since 2005. I graduated with a B.S. in Physics, with an emphasis on biological sciences from Loyola Marymount University, Los Angeles in 2004, and A Masters in Sport and Exercise Science in 2019. I also received certifications through the National Academy of Sports Medicine (NASM), the Aerobics and Fitness Association of America (AFAA), and most importantly, the CrossFit Instructor Level II certification. I’m also CrossFit Nutrition Certified, Crossfit Movement and Mobility Certified, Catalyst Athletics Weightlifting and USA Weightlifting level 1 Certified. I’m also currently pursuing my Masters degree in Exercise Science.

I got into fitness back when I was 13. As an overweight child, I was fortunate enough to have access to a personal trainer at my local gym who helped me lose weight and gain confidence in a particularly vulnerable time of my life. I continued on my own to study many facets of diet and fitness through high school and college. I was attending college in Los Angeles with the intent of becoming a physician. I would go to class during the day, then spend two hours in the gym 4-5 days a week before studying. Needless to say fitness fascinated me far more than Quantum Mechanics.

After graduating, I studied for the medical school entrance examinations, and got a job at the UCLA division of Dermatology as a lab technician. Fortunately, I realized back then that I would never be happy spending my days in a hospital. I felt like I could do more preventing sickness than treating it. After a year, I left UCLA, and got a job as a personal trainer.

In the Los Angeles fitness industry, I had the opportunity to work with clients of all types: athletes, cancer patients, injury rehabilitation clients, bodybuilders, weight loss clients, actors and actresses preparing for film roles, etc.

In 2007 I moved back to my hometown of Sacramento to continue to work with a new set of clients to help them accomplish their fitness goals.

In 2008, I found Crossfit after a bad back injury from a typical bodybuilding routine that had almost sidelined me a couple years earlier. I had been spending hours at a time in the gym, and the rest of the day in constant pain. I not only had a bad back, but bad knees, elbow tendonitis, a separated shoulder, and wrist pain so bad I would have to carry my dinner plate with two hands.

All the injuries I accumulated turned out to be a blessing in disguise. I discovered that the way to begin alleviating these problems was to move the way our bodies were designed to move. Pectoral flys, bicep curls, and the leg extension were out, and pushups, pullups, and squats were in. Upon incorporating these movements into my routine, I began to identify all my faulty movement patterns. This is when I discovered flexibility/mobility training and soft tissue work. All of these plus a diet that controlled inflammation completely healed my chronic pain,

In 2008 I couldn’t even do the Sumo Deadlift High Pulls  with an empty bar during “Fight Gone Bad” at my certification, and now I can pull 2.5x my bodyweight off the floor. I’m in the best shape of my life and am now on a quest to provide the same blueprint for a happy, healthy life to everyone by utilizing the CrossFit methodology.
