Growing up as a competitive athlete, he was instantly hooked and fell in love with everything CrossFit had to offer. Brendan has a passion for helping people in every way possible, from crushing PRs to living healthier lives.

“Over the last few years it’s become my main form of fitness and I’ve seen more improvements in my strength and conditioning than ever before. I love the intensity, the variety, the sense of community and the results I get.  CrossFit Walpole is more than just a gym, its a group of friends pushing you to be the best possible you.” – Brendan O’neil
