Throughout my life I have chosen physical fitness to be one of my main interests. I’ve ran the LA marathon a few times. I enjoy swimming, biking, hiking and whatever other outdoor activity comes my way. Within my current profession, endurance, stamina, and strength are much needed.

As a Retired Navy SEAL, I have stayed “in good shape”, but it wasn’t until I was introduced to CrossFit some years ago that my fitness level excelled. I have seen many variations of fitness throughout the years and have yet to see any that push me the way CrossFit does.

CrossFit, and it’s style of training, is good for anyone desiring to excel in their overall fitness. It can be used functionally in all areas of profession, including law enforcement, firefighters and military professionals.

I’ve been pursuing some kind of physical fitness for as long as I can remember. I based my fitness level off of various classes, which included advanced step, spinning, Bosu, and power step, along with some running.

BUT it wasn’t until I was introduced to CrossFit that I truly realized I was not well rounded in my fitness, nor did I realize the importance of “functional movements”, which is crucial in everyday life. I have 5 girls which keep me quite busy. My goal is to help others achieve optimal physical fitness through the CrossFit methodology.

I was introduced to CrossFit by a friend of mine in 2009. We started doing the WOD from the website and found it very challenging to complete the workout without the proper equipment and coaching. So, we found our local box and I joined CrossFit Simi Valley in 2010. I told myself that I would give it 3 months to see if I would get any results compared to my routine at our “globo” gym. I cancelled my “globo” gym membership after the first day and the rest is history.

My favorite thing about CrossFit training is that you can scale and modify for any level of athlete. Whether it be an adaptive athlete, someone with a temporary injury, or someone that is just starting out. The simple fact that an 80yr old grandmother and an elite athlete can work out side by side and do the same WOD, is amazing.

I truly enjoy coaching and helping people achieve their goals. I love watching our members support and encourage each other every workout. Friendships are made here and CrossFit Simi Valley has become a home away from home for many.

Challenge, commitment, community………That’s what CrossFit is to me.
