What Our Members Say
“My family love coming here! Everyone is so welcoming. The owners and coaches are amazing. Since my children have starting coming here I can see the difference in their confidence and coordination. Everyone is treated like family! There is no other gym like this one. If you never workout before the coaches are so patient and will help you. My family is so happy and blessed we found Proving Ground MMA! Thank you so much Ruben and Veronica!”
“I was in Surprise for a few months for work and was looking for a place to train while in town. I dropped in at Proving Ground and was immediately greeted by good people, good vibes, and high level jiu jitsu. Ruben and his coaches are great folks, and the training environment they’ve created is second to none. Whether you’re a veteran of combat sports or a day-one beginner, you’ll be welcomed and treated like family here. Can’t recommend this place highly enough!”
“My son has been here for almost 4 years and my husband and I have been doing it for 2 years. The coaches here are all amazing, environment is family oriented, everyone who shows up is super friendly too. I would highly recommend Proving Ground to anyone who is looking into something new!”
