Wilderness First Responder
I started rock climbing about 15 years ago on the Niagara Escarpment, and since that time I've travelled to climb every year, visiting many areas in North America, as well as Japan and recently Europe. My favourite climbing area is Red Rock Canyon outside Las Vegas, for the scenic beauty and variety.
While I started climbing using traditional protection and climbing mostly cracks, I love all the different types of climbing, from bouldering to sport to multi-pitch trad, and even ice climbing and alpinism.
The focus and excitement in climbing is something special, and something I love to share. It makes me happy to see someone I've introduced to the sport or taught achieve their goals and get excited to climb! I look forward to getting out and climbing with you!

I was introduced to climbing in my early teens and have been on ropes ever since. From climbing rock and ice to trees as an arborist, I feel at home in the vertical world, and enjoy all aspects of climbing.
​
In addition to climbing, I have many outdoor interests, from canoe tripping and biking in the summer to backcountry skiing and touring in the winter.
​
I am dedicated to working with both new and experienced climbers alike, passing on my knowledge and experience so they too can enjoy climbing and accomplish their goals safely.

Hi! I'm Oz!
​
I started rock climbing in 2014, and the supportive culture and inclusive community I encountered in climbing truly captured my heart. I am passionate about sharing this enthusiasm and these values in my everyday life.
​
I enjoy learning about outdoor climbing techniques and risk management, competing and coaching with the university climbing team, and working in local climbing gyms. Coming from a scientific background, I like to use these skills—such as careful, analytical planning and maintaining a mindful approach to complex tasks—when guiding climbers, ensuring their experience is both safe and fun.
An important part of my journey has been the realization that I find deep fulfillment in sharing my knowledge and passion for climbing. I also take great pride in tailoring lessons to accommodate all learning styles and skill levels, from beginner to expert.
While my goal is to travel the world, using my climbing skills to tackle ambitious multi-pitch climbs and big walls, I’ll always think of the cliffs of Ontario as home.
