Hi, my name is Chris Gonzales, and I am proud to be the owner of Boxing Fit University and a dedicated boxing coach from Tucson, Arizona. Born and raised in Tucson, I started boxing in 2003 and have been passionately involved in the sport ever since. I hold a Silver Certification in USA Boxing and am honored to now serve as a representative of Arizona for USA Boxing.

In addition to boxing, I am certified in TRX, CrossFit, Olympic lifting, and kettlebells, and I’m working towards obtaining my spin certification. I have a deep passion for teaching the sport I love and helping individuals achieve their personal fitness goals. My ultimate aim in boxing is to coach a national champion and a world champion one day, inspiring others to pursue greatness both inside and outside the ring.
