Make it stand out
See what people are saying about us.
“I highly recommend this guide service. They know the mountains like the back of their hand and are true professionals. I felt safe and learned a lot when climbing and skiing with them. They are also AMGA-accredited, which is something to look for in hiring a mountain guide.”
- Alex O.
“I have been climbing with the crew from Vertex Mountain Guides for 7 years now, both group mountaineering trips, ice climbing adventures, and education in the for of Avalanche training.
They are pros in what they do, not only that they make it super fun, adventurous, safe, and educational. It is like climbing with friends the whole day. Keith, Brendan, Ann are all fantastic at what they do and always have the client and the clients mission in mind while staying safe.
Very highly recommended as I start my 8 year climbing with them.”
- James M.
“A day that far exceeded my expectations!
Before Keith and I even met up, I was impressed and appreciated Keith’s flexibility in scheduling to make my trip. We worked around a few different weather situations that would have been a bummer.
Ultimately, the waiting paid off for a bluebird day to knock out a Peak to Parking Lot, something that had been on my bucket list for three years.
Despite the volume of touring and skiing, Keith was friendly and knowledgeable. He greatly expanded my comfort and speed of travel in the steeps/side angles and I left the day feeling much more comfortable in my ability to move in the mountains.
Can’t recommend enough!”
- Andy G.
“Highly recommended. Great knowledge, skillset and communication throughout the tour. Keith and Brendan were both willing and capable of assisting each individual's relative needs the entire trip, whether gear or skill related. Top notch hospitality.”
- Bill T.
“I’ve been working with Keith for years and he is an excellent instructor. He is very approachable and has a very intuitive approach to teaching safety systems, etc. I always come away having had a great day and learned a bunch.”
- Rob A.
“Keith is amazing and I can't recommend him enough! My climbing partner and I were looking for a guide who could help us prepare for our own adventures. Keith guided us on two multi-pitch adventures, on Cathedral Ledge and Mount Washington. We were able to repeat both trips on our own, safely and quickly, which was our goal. I learned an enormous amount working with Keith, such as micro-routefinding, better rope management, and suggestions for easier anchor building. We will definitely work with Keith again for another fun adventure.”
- Ben M.
“Keith and the crew at Vertex are the best guides in the Northeast by far. Been doing winter ascents with them for the last 6 years in the presidential range. They know what they are doing, are great teachers, and a lot of fun to be around. Highly recommend!”
- Dave G.
“Keith took my 18-year old son Nicholas and his friend to hike to and ski Tuckerman Ravine. This was the first time my son drove to another state on his own and it was his first time skiing Tuckerman, so I was a very paranoid and scared mom. Keith put me at ease. He was so chill and easy to communicate with. Extremely responsive. All I know is that my son and his friend loved it. They did it on April 19 and they skied Right Gully and Hillman’s Highway in one day. I really appreciate Keith keeping them safe and showing them a great time. Thank you so much!”
-Anna W.
“Only good things to say about Keith and Brendan's guiding. I have done two trips with them on Mt Washington and learned so much about decision making on safety, efficiency, and maximizing fun even in challenging winter conditions. Would recommend using them for not only beginners but advanced skiers that are looking to expand knowledge of terrain and skill.”
- Scott F.
“Keith Moon and his colleagues at Vertex Mountaineering are best-in-class in the Northeast. Not only are they highly skilled, but they also continue to hone their craft as lifelong learners. They hold the highest levels of professional certification and are outstanding teachers and mentors. I’ve worked closely with Keith in preparing for my climb of Denali. His guidance and support have been invaluable. On top of all this, they are simply great people. I hope they inspire many others to get involved in the outdoors. I would highly encourage you to consider Vertex Mountaineering to take your skills and appreciation of the outdoors to a higher level”
- Dave S.
“I've been learning from Keith since 2021. I've taken multi day avalanche courses, and had many objective focused and skill focused days and multi-day outings for ice climbing, rock climbing, skiing. I make time in each season to get days with Keith, because he tailors his teaching style to you and to your objectives for the day, but also for your goals across seasons and future adventures you may have planned. His gear and kit is always professional; He's always on time; His communication is excellent. I highly recommend Keith and his team.”
-Sean S.
“My Wife and I had Brendan as our climbing guide, what an incredible and truly memorable day. Not only did Brendan have expert knowledge of the area, he made us feel really safe, we knew we were in good hands with him. He was also incredibly funny and had us laughing the entire time. I cannot recommend Brendan enough. A day we’ll never forget! 10/10!!!”
-Austin K.
“Keith is the man. Awesome day at Tuckerman’s for a first timer. Keith’s made the day safe, fun and relaxed. Highly recommend Vertex form your next adventure.”
- Matt B.
“What an unbelievable experience! Getting to the summit of Mt Washington is certainly, "a task", but made substantially easier by the help and professionalism of Keith and his team. As a relatively novice skinner, they always kept the group in check, made sure everyone was properly guided, in all facets, and were just generally extremely helpful! They were absolutely essential in my accomplishment, and I would highly recommend their services!!”
- Chris C.
“Keith and Brendan are the best. Had the chance to spend a few days seeing them both in action helping us navigate almost zero visibility in challenging terrain with changing snow pack. Super helpful and fun, but more importantly always providing insight and education whenever asked or needed. If there was downtime they were both there and willing to share any nugget of knowledge you could ask for. Would highly recommend using them for your next adventure!”
