What Our Students Say
Hear from our community about how training at our academy has impacted their lives.
Carter Black
"Great gym! Been training here for a year and a half now. Definitely found what my main sport is with this place. Coach Dan Fazzino is great and everyone here is so supportive."
Tony Monchinski
"I’ve trained in a few BJJ places over the last decade and visited several. Whetstone Jiu Jitsu is a special place. What makes it special are the people and the vibe. Owner Dan and his wife Erin obviously love the sport and have created a welcoming, inclusive school. I’m an older grappler (50s, ten years in, purple belt) and what I appreciate most are the comraderie and the various instructors with their different styles. The gym itself provides a large mat space, a well equipped weight area (complete with squat racks, deadlift platform, reverse hyper machine, bands, dumbbells that go over 100 pounds, etc.), clean bathroom, ample parking, and a range of classes in gi and no gi, including striking, MMA, and plenty of open mat time. I highly recommend this gym. You won’t meet a better bunch of people and you’ll be surrounded by a highly skilled set of grapplers including several black belts who are competitively successful."
Mariana Brophy
"For almost four years, our family's been into Jiu Jitsu at Whetstone Jiu Jitsu. What started as a curiosity quickly turned into a real passion for each member of our family thanks to Dan & Erin's awesome guidance. Their support & encouragement have not only helped us improve our skills but have also created a sense of belonging within the Whetstone Jiu Jitsu community. We're really thankful for how Whetstone Jiu Jitsu has made a difference in our lives and can't wait for more years of training!"
Amanda Wiltse
"I cannot stress enough how much I’ve gained from training at this gym. The owners have a true dedication and passion, that’s matched by their knowledge and patience with both the adults and the kids. My kids and I train, not only have we leaned so much in a few months, but the positive members/parents have been an unexpected bonus. If you want a motivated, safe, clean, supportive, and engaging gym to train at whetstone is the place to go."
