  • “Koby was an expert in all topics covered. He took extra time to make sure everyone understood the skills being taught. Highlights for me were learning how to set snow anchors and crevasse rescue.”

  • “It was a blast. The routes and setting were amazing. Koby was as solid as can be… amazing knowledge, good host and steward of the forest/mountain. I had an excellent time.”

  • “I had an incredible experience on Mt. Baker. Koby was professional, personable, knowledgeable, and just excellent for the job. He made us feel very welcome and made for a really wonderful expedition overall. I’d been thinking about and preparing for this trip for perhaps 6 months. It exceeded my expectations and will stay with me for years to come. Really, a superb experience and I can’t say enough about it.”
