Our story
We still remember what it felt like to need this ourselves.
Kathryn and Geoff Belleville: partners in life, in love, and in business, with more than 43 years of combined experience in quantum biofeedback.
What we believe
The future of wellness is personal.
We believe quantum biofeedback is the future of wellness, because we believe the future of wellness is personal.
It’s so important that people know how to take care of themselves, and that, at the end of the day, they have a tool to do it. That’s why we believe every home deserves to have its own device.
We have questions we know we have, and we’ll help you find answers to those. What really excites us is helping people find answers to the questions they didn’t know they had.
Co-founder
Kathryn Belleville
Visionary, quantum educator and creative director
Kathryn has worked in quantum biofeedback for more than twenty years. Long before wellness technology was everywhere, she could see where it was headed, and she has spent her career helping people find their way to it.
She is an entrepreneur, a speaker, a coach and an artist, and she is the heart behind the feeling of The Frequency Boutique. Her hope is simple: that the moment you walk in, or even visit our website, you feel like you’ve walked into your own spa.
Co-founder
Geoff Belleville
Lead quantum guide, educator and business mentor
Geoff first experienced quantum biofeedback as Kathryn’s client at sixteen. By eighteen he had a practice of his own, and he has guided sessions for more than twenty years since.
Today he leads sessions, teaches every level of Quantum Biofeedback University, and mentors new practitioners on the business side of building a practice. He loves raising up practitioners, and he’s now raising up new instructors, too.
