Brad Eades

FIS Lead Coach

I grew up in Caledon Ontario where I first stood on skis at the age of 2. I was immediately captivated by the sport, and it has been a major part of my life ever since. I raced from age 8 through until I was 20. I spent a few years racing on The Ontario Ski Team before I started my coaching career. I started coaching with the Ontario Development team followed by the Ontario Ski Team and latter was the head coach for the SOD ski team before moving to Whistler. I fell in love with the mountains and all the endless activates that come along with this mountain town, I fell in love with the community creating friendships that will last a lifetime and I fell in love with the Ocean. I thrive on working in a team environment and coaching gives me a sense of connection and purpose unlike anything else. I believe in hard work while having fun. When the two come together, I believe we can do anything!

I am 29 years old and I come from Val d’Isere in France.

I am very happy to have the chance to coach this year in Whistler and I will do my best to create an environment that is fun and leads to good results to all athletes.

Zack Nattress

U14 Coach

Hi my name is Zack and I am one of the U14 coaches for the 2023-2024 season. I grew up skiing in Ontario where I raced for many years and then coached for two years before moving west. I spent the 2018-2019 season coaching in Whistler where I learned what real mountains are. After finishing my first season out here I went to school at Dalhousie University where I studied business and shortly after graduating moved back to Whistler. I’m excited for the season ahead and looking forward to continuing my journey as a ski coach and learning more about the mountains in British Columbia.


Soleil Patterson

U14 Coach

Originally from Rossland, BC, I started my ski racing journey with the Red Mountain Racers. I continued racing with RMR until I was selected for the BC Ski team in 2016, where I competed at a NorAm level. In 2018, I was fortunate to receive an athletic scholarship and joined the University of Alaska Anchorage NCAA Div 1 ski team. After dedicating 6 years to competing at an elite level, with a few setbacks along the way due to injuries, I made the decision to retire in 2021.
Shortly after stepping back from racing, I transitioned into the role of a ski coach. I began my coaching career at the Revelstoke Ski Club, working with U14 and U16 athletes. Despite my relatively short time as a coach, I’ve had the amazing opportunity to coach the U16 BC Team at Nationals as well as the Canada Winter Games. This year, I’m excited to be coaching the U14s and working alongside a great coaching staff at WMSC.
In addition to coaching, I am currently studying Graphic Design at BCIT. In my personal life, I am continuing my ski career in the big mountain/media industry supported by companies who have supported me for several years. During the summer, I compete in the Elite category of the BC and Canada Cup Downhill Mountain Bike Racing circuit.
This season, my goal is to promote excellence among my athletes. I aim to support them in understanding and expressing their motivations for participating in ski racing, whether that be within the sport or outside of the sport.

Aidan Walters

Aidan grew up skiing in Ontario on hills rather than mountains. Ski racing out east developed his love for the sport and has set him chasing the mountains across the country. Aidan spent 3 years racing FIS, two with the SOD ski team and one in Europe. He recently moved out to BC to study at Quest University and began his coaching career up at Whistler this season. This year he added an EL coaching course to his extensive list of certifications from summer-time wilderness guiding.
