My Journey

1. Getting Started

Wellness was not a value of mine for the first 13 years of life. My nutritional intake was undernourishing and most of my recreational activity involved sitting in front of a TV. Consequently, by the 6th grade, I had grown obese and my fitness level was so low that even a light jog was accompanied by laborious breathing and profuse sweating. During physical education class, I was routinely humiliated when I was chosen last for sports teams. Even worse, I was a prime target for school bullying.

Concerned about my health status and poor self-esteem, my mother started cooking healthier meals and enrolled me in swimming lessons when I was 14. Within seven months, I had lost nearly 30 lbs of body fat and exercise no longer felt torturous. I felt empowered by the transformation and surge of vitality, as I did not have a concept of health until I experienced it.

2. Getting Serious

At 16, I progressed to joining a health club and quickly built a physique impressive enough that many of my peers in high school and the gym regularly sought me out for fitness-related advice. This was the polar opposite of my social interactions in middle school. Taking pride in mentorships, I eventually decided to make my newfound passion a career and became a personal trainer in 2007. Since then, I have furthered my education by getting a Bachelor Science in Health Science and attaining multiple certifications in personal training and nutrition, as shown on my website.

Since 2007, I have trained a large diversity of clients-in both the health club and in-home settings- for a wide range of fitness goals. This included weight loss, strength and conditioning for various sports, increased mobility, and physique transformation. Out of the variety of fitness goals I helped my clients attain, improving the wellness of the elderly and those with chronic health issues, such as obesity and heart disease, was the most rewarding. My goal was to give them the experience of radically changing the course of their health trajectory as I had initiated with my 6th grade swimming lessons.

My fitness journey has introduced me to many hobbies outside the gym, most notably my love for outdoor activities: mountaineering, snowboarding, trail running, rock climbing, white water rafting, obstacle course races, and scuba diving. This gives my vigorous effort in the gym a greater purpose, which motivates me to regularly set new fitness goals, an enthusiasm I strive to conjure up in my clients.
