I joined the Army hoping to become an Airborne Ranger. I came to Rich not only because I knew the experience he had, but because I knew he'd be able to get me in the best shape possible to make it through my military career. The workouts we did were brutal and tough but he never let me quit! Amazing trainer! Would highly recommend if you want a motivating trainer and a kick ass workout plan to whip you in shape! Thank you Rich and Liberty Performance Training for preparing me!

Rich taught me to believe in myself. The best testament to this was my first powerlifting competition, where I placed second. This was a huge mental and physical accomplishment for me. I am very fortunate to have met Rich. He saw my potential long before I recognized it myself. He is always pumped up and is very passionate about lifting. This is reflected in our crazy and sometimes mentally challenging workouts. I feel extremely honored to work alongside such a phenomenal trainer. Thank you Rich!

Rich is not only great at working with my daughter on proper technique for running, lifting and training - he also provides her with with the mental toolset that is required to compete at a high level. That mental toughness and determination is what allows athletes to separate themselves from the competition. Rich understands this and incorporates it into his overall training plan. I would recommend Liberty to anyone looking to help their child improve speed, agility and strength. Thanks for everything Rich!
