Colette Broe-Johnson

Colette is our newest massage therapist here at Spectrum. She is from Bottineau, ND and went to school for massage here in Minot at St. Joseph's hospital through a course offered by Williston State College. She graduated with honors and an associate's degree in massage therapy, and has been a licensed massage therapist since 2007. She has always been drawn to solving puzzles and observing how things work together. This, combined with her love for helping people, is what she believes makes her the great therapist she is today! Although she isn't specialized in one specific modality, she uses numerous techniques to try to attain results by adapting and tailoring each massage to the individual and their specific needs.


Grace Giuliani

Grace's big smile is one you've probably encountered at Spectrum. If she's not working the front desk, she's either teaching class, participating in class, or partner personal training at Spectrum with her friends - THIS LADY IS A BEAST. Her passion is to encourage people to love their bodies, promote wellness & to lead by example of how a woman, coach, mother, and wife can thrive confidently and love their journey. In addition to being a spin instructor, she strives to make time to let her creativity flow through painting, design, and volunteering for local organizations.
