KNOW WHO YOU'RE
GROWING WITH

Hey, friends! I’m an Arizona native, but I like to think of myself as a citizen of the world. Just like with travel, I believe fitness is a personal journey that looks different for everyone and shifts with life’s seasons—it’s not meant to be confined to a box or a one-size-fits-all approach. I started coaching back in 2012 and was part of the first graduating class from NAU’s Fitness Wellness program, where I earned my Bachelor of Science in 2014. My goal is always to help members grow—physically, mentally, and emotionally—through intention, commitment, and a whole lot of good music and movement. When I’m not on the mic, you can usually find me soaking up the sun in Sedona, running with my husband and our Weimaraners, or spending time with friends. My mission with The Box Studio is to empower our amazing community through positive energy and help people live better lives through mindful, safe, and fun movement.

Hi, I’m Florian—Cierra’s husband and your friendly French spice! I’m a dual citizen, born in France but raised everywhere from Sedona to the Virgin Islands. You’ll probably catch me working out next to you, though I leave the coaching to S/Cierra’s and the rest of our incredible team. When I’m not in the studio, I’m teaching at NAU or planning our next trip abroad! Whether you need help with your membership, bike setup, or just want to chat about English literature, I’ve got you. My mission at The Box Studio is to make sure your experience is smooth, seamless, and genuinely enjoyable from start to finish.

Hey there, I’m Sierra Robinett! I was born and raised in Arizona and I am a lifelong lover of movement. My fitness journey kicked off back in high school as a competitive track and cross-country runner, and since then, I’ve fallen in love with trail running. These days, I compete in everything from half marathons to ultras. I’ve been immersed in the fitness world since 2016 and have been a certified group fitness instructor since 2017. Outside the studio, you’ll find me soaking up the outdoors with friends, traveling with my amazing wife, or snuggled up with our pups. My mission at The Box Studio is to create a space where movement is both safe and challenging—and where every class leaves you feeling empowered, inspired, and stronger than when you walked in!
