Meet Your Guides

Acadia Mountain Guides Climbing School is a company of professional guides. Since our inception in 1993, we have required formal training and evaluation of all our guides simply because it was the right thing to do. Our guiding standards are among the best in the industry and represent the highest standards in Maine. Our guides are friendly, dedicated professionals whose talents lie in their technical expertise, climbing ability and their skill as educators. The quality of our guides is what makes Acadia Mountain Guides Climbing School your best source for climbing instruction.

Our guides are veteran climbers with several years of diverse climbing experience. By requiring in-house specialized guide education courses we maximize competency and efficiency and greatly reduce risk. Our greater efficiency allows more time to teach you important skills, and to provide you with more climbing opportunities without feeling rushed. All are also certified at or above the Wilderness First Responder level of medical care. Our internal training keeps everyone up on the latest techniques and current on the best local practices.

We are committed to providing you with the best climbing experience possible. It is our goal to provide a supportive climbing environment that maximizes your time and minimizes your risk. Our mission steers us to continually develop cutting edge ideas and techniques that improve the delivery of our instruction. Many of these ideas have become the foundation both the AMGA and PCIA training programs. We believe that the guiding art requires extensive climbing experience and a multi-faceted educational background. We take our philosophy to heart and work to promote responsible climbing and wilderness use as well as responsible guiding on both a local and national level. We are proud to be participating in the development of professional standards that other guide services can only aspire to. Simply put, we are attentive to the details.

We look forward to sharing our love of high places with you and invite you to take a look at our backgrounds.
