Jackie Adamek

Studio Director, Senior Instructor

Meet Jackie
  • Hailing from the land of 10,000 lakes, Jackie has found herself right where her heart belongs in Montana.
  • Fully grasps the “work hard, play hard” lifestyle with no attempt to tame her wild heart.
  • Full-time instructor and operations manager at Zephyr, dog-mom to rescued homeless pup Lola and Beartooth the Pug, smile and laugh-addict, Jackie lives to motivate others.
  • Jackie brings the “jamz” (and yes, with a “z”), positivity, and energy into her classes where she not only wants people to sweat, but to ALSO have a helluva time doing so.
  • Don’t let the blonde hair (and other arrays of pink pastels) or giggles fool you – Jackie comes ready to bike hard every class. She loves the feeling of the music guiding every pedal stroke along with the energy every person brings to each class.

Demi St. John

Operations Director

Meet Demi
  • A midwestern transplant to Montana who fell in love with the mountains during her high school days.
  • Discovered indoor cycling in college and has pursued the joy of it ever since (just ask about how she joined our team!).
  • Has an eye for the details and enjoys bringing a new perspective to the Zephyr team with her science/engineering background.
  • She’s always down for a quiet night in or conversation over coffee!

Devin Archilla


Meet Devin
  • A lifelong adventurer, Dev hopped around the globe and coast to coast growing up. She found herself moving to MT for college and has yet to leave.
  • Dev graduated with highest honors in Graphic Design and Entrepreneurship from Montana State University in 2014. 
  • When she’s not sweating it out at Studio Barre, Zephyr, or pumping the weights, you can find her in the mountains hitting the trails all season long with her hubs Mark and fluffy Border Collie/Pyrenees adventure pup, Thor. 
  • For as long as Dev can remember, she has always enjoyed being physically active. Breakfast is her all time favorite meal, and most days she’s up and on her second cup of coffee for the sunrise.
  • Dev now runs her own photography business, Devin Helen Boudoir, through which she takes her own unique twist on empowering women through photography. Interested in learning more? Check out her website at
  • Why does she want to teach at Zephyr? Simple. For people to believe in themselves. To let go, and to have a freaking fun time not only working their bodies, but also their hearts and their minds.

Sage Chase

Instructor, Front Desk Staff

Meet Sage
  • Born in Wyoming, Sage is a western girl through and through.
  • Moved to Montana in high school and fell in love with anything to do in the outdoors. A few favorites include hiking, skiing, and snowshoeing! Fell in love with spin after her first class at Zephyr and found that positive music mixed with positive body movement regenerates the body, mind, and soul.
  • Sage is a senior at Montana State University studying microbiology.
  • Dog mom to the sweetest Border Collie, Huckleberry.

Maddy Halvorson


Meet Maddy
  • Grew up in the flat lands of North Dakota but after visiting Montana regularly with her family, she fell in love with the landscape and people and couldn’t picture herself living anywhere else and is pursuing her degree in Elementary Education.
  • When not at the studio, you can find her hiking, fishing, and skiing. She loves to cook, travel, and spend time with family and friends and is also a server over at Nordic Brew Works. (Cheers!)
  • Found her passion for cycling when she visited a West Coast studio. When she discovered Zephyr in Bozeman, her heart immediately knew she had found a studio where she fit in and felt at home.
  • Maddy’s favorite way to move is to dance on the bike. Being an instructor to her means inspiring others to believe in themselves and to love who they are.
