Meet our Staff

Joe Santo


Joe began climbing in 2017 and has been obsessively pursuing the sport ever since. Since joining the MetroRock Everett team in 2019 he has been involved in all manner of gym happenings, landing in Littleton in early 2020. When not in the gym or at a crag, Joe can be found skiing, running, or fishing in the mountains. He is looking forward to exploring some of the local climbing in the greater Littleton area in the coming months.

Chief Route Setter
Zach Larson aka ZEL

Zach started climbing when he was 5 years old and as a youth climber was on the US National team twice. He began route setting in Everett, MA in 2014 with his brother Josh Larson, who is Head Coach for the USA Climbing team, and the legend himself Dave Wetmore.

As a setter, Zach has created routes for the highest level rope competitions, as he set for the 2019 Rope and Speed Youth Nationals. Zach has also set for our bouldering competition Dark Horse, for the past 6 seasons and has many other competition level sets under his belt.

Besides climbing, he enjoys hiking with his dog Titan and fishing for lunkers (aka large bass). Follow him on Instagram: @Larsony95 


Programs Coordinator & Head Coach
Steph Chaddock

Steph grew up in Massachusetts, but spends enough time at crags to the north that she calls New Hampshire home. She went climbing for the first time when she was 12 years old at her local gym in Nashua, NH. Ten years later, she began working as a youth coach and there discovered a passion. Steph regularly boulders and sports climbs, and has recently started trad climbing.

She does most of her climbing outdoors at popular New England spots like Pawtuckaway and Rumney, but has also taken trips to Red Rock Canyon in Las Vegas and the Red River Gorge in Kentucky. Those who know her well know that she’s up for climbing rain or shine and is always up to support others in their goals.

In addition to her passion for climbing, Steph loves photography and can be found at the crag photographing her friends and strangers hard at work.
