Together, you'll form a team to assess and manage risk while you receive real-time feedback and tips for improving your movement and technical skills from an accomplished climber.

Your guide: dustin portzline

When you hire Dustin, you receive the full attention and care of an experienced guide in his prime. Dustin has been guiding professionally for ten years. He is certified, licensed, insured and permitted. 


Dustin has been living and guiding in the Gunks since 2010. Born in Chicago and raised in central Pennsylvania, he discovered climbing in his teens and has never looked back. Years of technical training, immersion in the climbing lifestyle and varied natural landscapes has given Dustin an intimate understanding of the challenges and rewards inherent in climbing. He lives in Gardiner with his wife Amelia and their talus hound Chloe. 



Dustin’s mentorship has unlocked a whole new world for me to explore. Not only is he incredibly thoughtful and generous with the hard skills he teaches, he is excellent at coaching mental development. He is an expert climber and guide, but continues to maintain a voracious appetite for continued learning and improvement. I can honestly say that setting up a “learn to lead” course with Dustin four years ago was one of the best investments I have made.

As usual you continue to exceed expectations and inspire me to exceed my own. What a great trip for both learning and experience. The weather was a bonus.. Hope to see you soon with all of my new skills practiced to perfection.

Thank you so much for working with our son last week. He had the best experience. He enjoyed the challenge of the outdoors, putting his gym climbing skills to use and learning new ones from you!

Thanks again for your ice climbing teachings. I had a fantastic time and was way more comfortable on the ice than I had ever imagined.

Michiel and I had a fantastic day out. The day was beautiful, the climbing excellent and Dustin was the ultimate guide. He is super competent, fun to hang out with and somehow knew exactly which routes we would enjoy. Dustin (and the quality of the routes) made our day memorable.
