Bronwyn is a professional rock climber and guide, based out of Squamish, Canada. Originally from rural Ontario, she grew up canoeing, hiking and skiing with her family. She started climbing at university and immediately fell in love with the sport.

Bronwyn has climbed 14a sport and 13d trad, as well as many adventurous routes in Europe, northern Africa and North America. In November 2018 she became the first Canadian female to free climb El Capitan in Yosemite, CA, with her ascent of Freerider (13a) over five days. That was her fourth attempt in as many years, and a huge personal goal. Three years later she became the third women in the world to free climb Golden Gate also on El Cap.

She has also lead remote big wall expeditions, including a summer on Baffin Island in 2019 with her husband Jacob and two of her childhood adventure buddies, Thor and Zack. On the trip, the team climbed some big mountain faces including Mount Asgard (three times!) and Mount Thor, and accessed the mountains by packraft making the trip self-propelled from the Inuit community of Pangnirtung. In 2022 Bronwyn and Jacob and four other friends traveled to Greenland, where they established new big routes on sea cliffs which they accessed by sea kayaking 400km of Arctic coastline!

Bronwyn is also an ACMG Rock Guide, guiding and instructing seasonally around Squamish, BC.
