    ­​My racing career started at the age of 12 in northern California, After my first race, I was hooked and there was no turning back! I turned pro in 1997 after racing Loretta’s, then graduated to the nationals full time. I entered the AMA Pro scene as a member of the factory Husqvarna team in 2000 and was able to race 6 nationals on their 125 two-stroke.


    Not only a racer, I worked for Honda from 1999 to 2005. I was instrumental in helping develop the Honda line of powersports equipment. During my time at Honda, I tested groundbreaking machines and worked hand-in-hand with top industry engineers. Also, I've been working with Motocross Action Magazine as a photo rider, parlaying expertise into a position as the Assistant Editor for MXA in 2007.


    In 2012, I got serious about riding schools and motocross vacations, so I started KnobbyShop. Due to my traveling all over the world, I was able to meet some great people in other countries and now I have them travel to come stay with me in Southern California enjoying the mecca of motocross in sunny southern California!

    I grew up around dirt bikes. Camping and riding throughout the desert was our regular family time on all holidays and weekends. My first track experience was in 2014 and I fell in love with it. I participate in local races and have a great time riding with my friends regularly. I started helping Dennis with the paperwork side of his business in 2016 and enjoy working with Dennis and his dad on a part time basis. My full time job is at a company called NETSTOCK where I am the Finance Operations Supervisor, which provides me with the ability to balance the two jobs.­
