I joined this CrossFit Mischief about a month ago and I’m really happy with the experience so far. The atmosphere is positive, motivating, and very supportive. Big shout-out to the coaches — Tobias, Arianne, and Christie — they’ve been amazing! As a beginner, I appreciate how the workouts are thoughtfully modified to my level, while still encouraging me to push a little further each time. The support I’ve received has given me a lot of confidence, and I already feel like I’m on track toward reaching my goal of losing weight. Highly recommend this place if you’re looking for guidance, motivation, and a community that truly cares about your progress! -Mani

I dropped in while visiting from Phoenix. Coach Alex was amazing, so knowledgeable and made class so much fun! The gym is spotless!✨ The members were so helpful and friendly, you can really feel the sense of community CrossFit Mischief has from the second you walk in the door. I will definitely be dropping in next time I am in town. Thanks for a great workout while on vacay!

Eight and a half years ago, I walked into CrossFit Mischief not knowing just how much it would shape me. It’s still the hardest workout program I’ve ever done—but, it’s been the best thing for me. What keeps me coming back isn’t just the challenge, but the incredible community and the coaches who go above and beyond. They offer modifications, push us to grow, and help us to make every workout doable—no matter where we’re starting from.

This was my first ever experience with CrossFit and honestly, it couldn’t have been a better intro. Everything at this gym is just dialed in—super well-organized, form-focused, and run by people who genuinely care about your growth and safety. The community here is also something special—friendly, motivating, and full of good energy. You never feel out of place, no matter your level. Huge shoutout to the coaches Arianne, Jake, and Erach—absolute legends. Their attention to detail, constant support, and ability to push you in the right ways made every class something I actually looked forward to. They create an environment where you’re challenged, but never overwhelmed, and always encouraged to get better. If you’ve even thought about trying CrossFit—or just want to be part of something that pushes you, supports you, and leaves you walking out stronger every time—stop scrolling and pull up to this gym. You’ll know exactly why from day one.
