Gillian Simpson 

Master Trainer, Canada

Gillian was introduced to deliberate cold exposure after her third baby was born.  When her daughter turned 3 months old, she attempted her first ice bath, and was immedaitely hooked! Not only was it the most invigorating and empowering feeling she had ever felt, it took her right out of her funk; postpartum depression and hormonal dysfunction. 

A rockstar firefighter in her earlier career, Gillian knew how to lean back into becoming a role model for females in this new space. As she recognized the power of the ice bath, she made it her passion, career and life focus to share breathwork and cold therapy with others. 

Becoming one of the first Canadian SHERPA Breath & Cold Instructors in 2022, Gillian took her training to the next level and opened Canada's first Guided Breathwork and Ice Bath Studio - ‘For The Love Of Ice’.  Less than a year later, Gillian was invited to train into the SHERPA Master Trainer she is today. As she undertook the rigorous work to ready herself for training other instructors, she deeply understood that she's landed exactly where she is supposed to be -  rocking her business in Ontario, staying sweetly in Mom life, and sharing the magic of this program with a larger global community.

Jeremiah Davidson

Master Trainer, US

Jeremiah is Colorado raised with southern roots, a true lover of country mountain life. When he’s not on a yoga mat, he’s probably nestled under a ponderosa pine or singing songs around a campfire. 

Jeremiah’s early years were filled with a wondrous spirit of adventure; he has lived across a few different countries in a handful of urban settings and rural countryside.  Amidst his travels, he managed to complete an undergraduate degree at the University of Washington and a graduate degree in psychology at New York University.   

Jeremiah’s first ICE experience was during a plant medicine retreat in California.  While completely shocked with both intensity and wonder, Jeremiah felt an inner calling to work with ICE.  He leads group and individual focused offerings across the Denver metro area.  Jeremiah loves the energy created during team sessions and the vulnerability of individual practices.  Merging science and spiritually, Jeremiah speaks often to the human historical use of breath and sacred water for healing.
