I’ve never met a guide who is as knowledgeable, skilled, and most of all calm and collected as Justin
“I’ve climbed with Justin at Skyline multiple times now and I can honestly say, compared to the various major guiding companies I’ve climbed with, I’ve never met a guide who is as knowledgeable, skilled, and most of all calm and collected as Justin. Every time I feel like I don’t know something or got myself into trouble Justin has always gotten my back. He always knows exactly what to do and when to do it, is extremely diligent, and ALL while being the most fun and entertaining, coolest dude ever.
I love every single climb I’ve done with him, learned so much while having a great, confident time. 100% recommend over any other guide.”
