Isaac Bernstein

Isaac has been an avid outdoorsman since his childhood. He began pursuing the outdoors in middle school, building shelters in the woods and hiking in nature preserves in his hometown of Sudbury, Massachusetts. Through high school he continued his passion for the outdoors and took part on longer backpacking trips and then planned out his own trip on the Long Trail. Isaac began climbing in high school in a gym, primarily as a boulderer. When he started college at Northern Vermont University in Johnson Vermont, he began climbing on ropes and progressed quickly. Isaac is an AMGA Certified Single Pitch Instructor and is training to participate in an AMGA Rock Guide Course.

Isaac enjoys all forms of climbing including (but not limited to) trad climbing, bouldering, multi-pitch climbing and ice climbing. His experience has been primarily in the northeast with many days spent on rock and ice, though he hopes to take his passion of climbing to many different parts of the world.

Evan Kirk

AMGA Single Pitch Instructor, Front Desk Staff, Youth Program Staff 

Climbing since 2010, Evan joined the Petra staff after moving to Burlington to finish his undergrad at UVM. While he believes any climbing is great climbing, you’ll have to twist his arm to get him to clip bolts or pebble wrestle because he’d much prefer to be two pitches up plugging gear all day long. If he’s not rock climbing he’s running, mountain biking, cycling, hiking, skiing, ice climbing, or generally, doing anything that doesn’t involve water (unless that water is frozen of course). Evan usually works the front desk, but also works summer camps and birthday parties and enjoys helping new climbers gain the confidence and skills they need to have a great time on the walls. He looks forward to seeing you at Petra Cliffs and hopes to see you at the crags too!
