Been training climbers since 2016, back when climbing was just emerging as a global competitive sport.

With the years of experience as a Personal Trainer, Korean Youth National Team Coach, University Team Coach, National-Level Competition Routesetter, and Outdoor Guide,

I help climbers of all levels rediscover the pure joy of rock climbing on and off the wall surfacing beyond the uncharted territories.

Reviews

Testimonials of Current and Past Clients


"Oscar is a patient, kind, and highly responsible trainer. I highly recommend working with him for anyone interested in developing a deeper relationship with climbing"

Logan

"He knows his stuff when it comes to getting better. His understanding of technique is on another level, and he catches things I never would’ve noticed on my own."

Jackie

"Oscar works one on one with you and creates boulders on the spray wall that really tackle your low hanging fruit, finding small tweaks to progress or regress in difficulty to make sure you’re trying just at your limit without things feeling discouraging."
