Mary Letson
Founder Positively Fit Training Studio, ACE certified Health & Wellness Coach, BCRPA certified Personal Trainer, Yoga Instructor and UK trekking guide enthusiast
Mary stumbled across her passion for fitness leadership in 1984 and dabbled in part time coaching until 1997. Realizing that inspired fitness coaching was her calling, she launched Positively Fit in ’97 and has since honed her skills and built a team of skilled trainers to address the breadth and scope of Bowen Island’s fitness aspirations. In 2006, she opened Bowen’s unique, boutique style gym providing all the right equipment in a light-filled oasis tucked away in Snug Cove. Along with Health & Wellness Coaching Mary has completed training in Osteofit, Third Age, 200 Hour Yoga Teacher Training, and has a double degree in History and Communications from SFU. Her love of adventure fitness takes her to the UK every year to host Cornwall trekking tours that combine daily walking with stunning scenery, divine food and superb accommodations. Her combined love of fitness and passion for her community has culminated in numerous events including TRI for CHAC, Aaron’s Run, The Reindeer Run and most recently in Bowen Island’s sweetheart event SwimBowen.

Rylie Treuer
Kinesiologist (BSc), Personal Trainer, Spin Cycling Coach
With a degree in Kinesiology and a love for exercise, Rylie strives to inspire others to move their bodies as a form of medicine. She believes in the power of movement to support our physical and mental well-being and improve our quality of life.
Growing up on the North Shore has shaped Rylie’s love for the outdoors and made spending time in nature a big part of who she is. If she’s not in the gym then you can definitely find her amongst the mountains & trees.
Rylie is passionate about helping others feel stronger, more confident, and capable in their everyday lives. Her goal is to create an encouraging and supportive environment where everyone feels empowered to show up for themselves, work toward their goals, and build sustainable habits that last a lifetime. For Rylie, fitness is not just about transforming your body; it’s about investing in your health, building resilience, and creating strength for life!
