The snowboard and ski instructors at Ski Sawmill are far from "just kids they let ski for free". Ski Sawmill takes every lesson and instructor very seriously and expects them to act professional at all times and give 110% of their attention to their lesson. Although most instructors are kids, each and every one has been through a training session. Most are not PSIA/AASI, but all that means is you've taken a test to get your "official" level 1, intermediate ski/snowboard thing that gives you discounts at other ski resorts and other small benefits. But, at the Sawmill, they have sessions once a month for an hour to two hours based on learning how to better themselves in teaching lessons. Being kids, it's hard to keep them acting professional every single second of the day, but I'm very impressed with them. If actions are taken too far (or even slightly), there are very serious consequences for everyone. At Ski Sawmill, they take Lessons very seriously and I'd highly recommend taking a lesson there. At larger ski resorts, they are only allowed to teach you on thing per lesson. At Ski Sawmill, the lesson is taken to the highest level possible based on your abilities. They may not officially be professionals, but you will definitely be satisfied with a lesson.
