    in my free time I like to
    Spend time with my daughters and wife in the great San Diego outdoors. We love to go hiking, spend time at the beach and traveling in the U.S. and abroad. I also love surfing, running and weight training. Reading and attending live concerts are also a nice luxury.

    Pain has been a constant variable on my mind ever since elementary school. I suffered from chronic lower back pain, shoulder pain, knee pain, and ankle pain. This never ending increasing pain led me to aspire to understand as much as I could about the human body from an early age, especially while obtaining my bachelors in Kinesiology. Regardless of what your perfect balance of fitness factors are, I believe the only non-negotiables’ are effort and persistence. I strive to create authentic, meaningful relationships with my clients and view myself as more of a teacher than a trainer. I want you to walk away with the confidence that you can train yourself without the overwhelming struggle required to understand the complex underpinning mechanisms required to make practical decisions. So let me save you years worth of struggle and time and lets create a purposeful results driven program designed 100% for you!

    in my free time I like to
    Be an awesome father and loving husband. I live for quality time with loved ones, going on adventures, hikes, and anything in the great outdoors. I have a deep curiosity and desire to learn as much as possible related to self improvement, life, the human body, philosophy and psychology.

    I have been involved in fitness for as long as I can remember. My mom was a personal trainer when I was younger, I would see her working out and would always be so interested in what she was doing. I started playing sports around age 8 and ended up playing basketball and riding horses through high school. In between the sports seasons, I would be in the gym lifting and pushing myself to always be better. Working with clients and seeing their confidence grow as they progress is by far my favorite part of personal training. Everyone has a unique reason for stepping into a gym. I love that I am able to help each person reach their goals. As someone who struggled with back and knee issues, the trainers I have had in the past made such an impact on my life. They helped me heal and reduce pain, pushing me to be better in many aspects of my life. I aspire to create an environment for training that is fun, encouraging, and motivates each individual to push each day to be better than before.

    in my free time I like to
    I love to explore the beautiful landscape Southern California offers as well as pursue my other hobbies such as makeup, cars, and reading. I am thankful to live near family so I am able to spend time with them whenever I get the chance.
