CWA Climbing Wall Instructor Provider Since 2025
Wilderness First Responder Since 2006
Kevin is a career outdoor educator with 20+ years of experience across scouting, wilderness therapy, commercial guiding, and most recently 14+ years in collegiate recreation all over the US. He has a Master of Science in Recreation and Sport Management from the University of Tennessee, Knoxville. He currently lives in Lowell, MA with his wife, daughter, son and dog.
In 2024 he started a new chapter in his career centered around family, outdoor adventure and entrepreneurism, becoming the owner of Greater Boston Climbing School in January of 2025.
Kevin specializes in mentoring intermediate climbers as they develop a foundation of movement, judgement and technical skills to climb independently. If you’re transitioning from gym, want to learn TR or traditional anchors, or maybe spend a day drilling basic self-rescue skills, a session or two with Kevin will really help refine your systems, skills, understanding and confidence. Kevin has also been climbing with his kids since they were old enough to walk. He very much enjoys facilitating family outings!

Ucraft Climbing Brand Ambassador
Ryan lives in Providence RI with his dog Rascal and has been working in PVDs high-end hospitality venues for the past 20 years. Ryan has an affinity to the outdoors and his 10 year progression through the climbing disciplines has naturally led him to want to share his experience and love for climbing with the amazing surrounding community!
Moonboard problems are Ryan's training grounds for hard outdoor bouldering and sport climbing, pushing V9 and 5.13 project grades. Traditional climbing has transformed from an interest into a passion to strive for excellence in movement and techniques while on the mountains. Ryan's goal is to continue to learn and grow in the local community while also giving back and being a steward to our outdoor spaces!
Come climb with Ryan and learn how to overcome your fears by progressing at your pace in a challenging and fun environment!!
Casey Rubidoux (he/him)
Instructor
AMGA Single Pitch Instructor since 2025
Wilderness First Responder
Casey grew up exploring the woods of Massachusetts climbing any tree he could find as well as rocky outcrops. However he didn’t truly find rock climbing until college while he was attending UMass Lowell studying electrical engineering. During this time he became an active member of the universities Indoor Climbing Club and Outdoor Adventure Program Leader.
Participating in these programs led Casey to become an avid indoor and outdoor climber which brought him to finding a profession in climbing at both Greater Boston Climbing School and Acadia Mountain Guides. While working in Acadia Casey Became a Single Pitch Instructor and brought stoke to instructing on the sea cliffs of Maine.
When Casey is not instructing climbing he enjoys spending time both sport and trad climbing at areas such as Rumney, Crow Hill, and Farley Ledges. And when he's not climbing he loves backpacking, canoeing, and spending time with his dog Zoey.
Howie Kalter (He / Him)
Instructor
AMGA Single Pitch Instructor Since 2022
Wilderness First Responder Since 2016
Wilderness First Aid Instructor Since 2018
I am a passionate rock climbing instructor and educator dedicated to helping people build confidence, skills, and a deep appreciation for the outdoors. I have been a certified Single Pitch Instructor since 2022, a Wilderness First Responder since 2016, a Wilderness First Aid Instructor since 2018, and a Leave No Trace Educator since 2021. The experiences and knowledge that I have obtained through these various trainings and courses allow me to prioritize safety, stewardship, and preparedness while working in the outdoors.
In addition to guiding, I work as a mathematics instructor at Phillips Academy, where I focus on helping students develop strong problem-solving skills. This teaching experience shapes my approach to guiding, as I strive to make technical skills accessible and engaging.
I enjoy working with climbers of all levels. I especially love teaching new climbers how to understand and mitigate the risks of climbing outdoors. Above all, I aim to create experiences where people feel safe, challenged, and—most importantly—are having fun on the rock.
