My Journey
I grew up in Tennessee, where much of my early life was spent outdoors- always in water, exploring forests, and developing a deep curiosity about the relationship between people and the natural world.
That curiosity led me to complete a Bachelor of Arts in Environmental Studies, with a minor in Economics, at the University of Tennessee. My studies explored the intersection of ecology, human behaviour, policy, and systems thinking—an education that continues to influence how I understand health, community, and our relationship with the living world.
As a lifeguard, swimming instructor, summer camp counsellor, and later an Interpretive Park Ranger, I learned how to guide people through experiences that fostered awareness, community, curiosity, and connection.
While interning at the Environmental Institute at the University, I was dreaming of the mountains and a completely fresh start. I accepted a job out west in Keystone Colorado as a Children’s Snowboard Instructor and moved within a week of receiving my Bachelor Degree.
Snowboarding took me to Colorado and Utah, New Zealand, and Australia, where I worked as a snowboard instructor and eventually earned advanced certifications through the Professional Ski Instructors of America PSIA and the American Association of Snowboard Instructors AASI. I was deeply involved in my community, working multiple roles and interacting with such a variety of people. Those snow seasons became a place of adventure, challenge, humility, and presence – extremely valued experiences and relationships.
In 2012, I moved to Australia.
What was initially intended as one season at Perisher became my new life! In those early times, I transitioned from the continuous winters, perfectly securing the role as a manager at a local snowboard shop. Around the same time I began practicing yoga at a studio up the road, shortly after completing my first 200 hour yoga teacher training in 2014 and the studies continued with 300 hours and additional qualifications in prenatal, postnatal, children’s yoga, yin yoga, and I’m currently completing a yoga course for women in life’s transitions of Perimenopause and beyond.
After navigating a difficult period in 2016 that included a collapsed lung in Mexico, post-wedding blues, and patterns of coping that no longer served me, I committed myself more deeply to practices that fostered genuine healing, responsibility, and self-awareness.
Between 2017 and 2019, I gained more qualifications as a yoga teacher, accepted the opportunity as a Lululemon ambassador, taught regular yoga classes in Canberra, and offered fortnightly après yoga sessions in Jindabyne. During this time I was also offered a position teaching snowboarding again at Perisher—an opportunity to reconnect to my roots—though life had other plans. By the end of that year, I was preparing to become a mother, expecting my first and completing my 300 hours additional yoga training then starting Prenatal Yoga Training while still teaching and running workshops and fundraisers as we welcomed my first daughter into this world.
Motherhood became one of my greatest teachers.
It deepened my understanding of nervous system regulation, embodiment, seasons of life, identity, and what it truly means to live in alignment with one’s values rather than external expectations.
In 2022, I discovered Rebirthing Breathwork Mastery, now known as Breathwork Mastery RBM.
What drew me in was not intensity, but gentleness. The emphasis on intention setting, parasympathetic activation (over the popular sympathetic styles), body awareness, self mastery, and integration felt deeply aligned with the principles that had guided my work for years. I went on to complete a 2 years of professional training with Eleanor Mann, the holder of this lineage through The School of Breathwork and continue to deepen my studies and practice with their amazing support for alumni through continuing education and collaboration.
Today, I weave together the many threads of my life from environmental education, snowsports education, yoga, somatics, breathwork, motherhood, and facilitation under my business, Alpenglow State.
My work supports people to slow down, reconnect with themselves, and cultivate the inner resources needed to navigate life with greater presence, responsibility, resilience, and joy.
Because beneath all the methods and modalities, I believe most people are searching for the same thing:
A way home to self. To remember who we are.
You can find me sometimes covering yoga classes at Wild Studio Canberra and KIND Canberra and sometimes SOULution Yoga.

Life has my super busy raising my 3 daughters, forming a solid foundation so they may thrive is my biggest priority.

What I am up to?
I live in Canberra, Australia with my husband, three daughters, and our kelpie dog, Smoky. My work brings together yoga, breathwork, somatics, women’s circles, seasonal living, and over two decades of experience guiding people through learning, growth, and transformation.
Outside of my work, I find joy in simple things: tending our home and cooking nourishing meals, building meaningful connections within our community, walks with my Kelpie, camping trips, F45 training, and sharing life with my family. As a lifelong snowboarder, I’m especially looking forward to teaching my oldest daughter to snowboard and getting my toddler on skis this winter. More than ever, I’m interested in living a life that feels connected, intentional, and wildly resourced—while supporting others to do the same.
