"Jon is a very experienced professional guide and one of the best educators in the AMGA. His client care and technical skills are excellent." - Rob Hess (former AMGA Technical Director and Bela Vadasz (IFMGA Guide)

Jon is certified internationally by the IFMGA / AMGA and examined and certified at the highest international standard by the AMGA as a Rock Guide, an Alpine Guide, and a Ski Mountaineering Guide. Certification in each discipline requires passing a rigorous multi-day peer assessment exam. Jon began climbing as a teenager in the mid 70's and came to Maine in 1982 and fell in love with the pink granite of Acadia. In 1984 he co-founded Maine Bound, the University of Maine outdoor program which he directed until 2001. During the summers in the late eighties and early nineties Jon traveled west to work for the National Park Service as a backcountry climbing ranger and paramedic. In 1993 he gave up the annual migration westward to established Acadia Mountain Guides as a summer guide service serving Acadia National Park. In 2001 Acadia Mountain Guides became a year round guide service offering not only rock climbing instruction by also ice climbing and mountaineering. With a passion for rock, snow, and ice, Jon's accomplishments as a climber and guide include over 75 high altitude peaks as well as difficult first ascent rock and ice climbs and hundreds of multi-pitch rock and alpine routes around the world.

Jon has been dedicated to wilderness education for three decades. Seeing a need for improved professional standards in guiding, Jon became actively involved in developing nationally recognized guide education programs. He has served multiple terms on the AMGA board of directors and was the chair of the AMGA accreditation program for several years. He has strived to synthesize good concepts, challenge usual paradigms, and develop new ideas to raise guiding standards. From 1997 - 2006 Jon led the development of the AMGA Top Rope Site Manager program which was the precursor to the current AMGA Single Pitch Instructor program. He most recent project has been to co-found the Professional Climbing Instructors Association, an organization specifically committed to developing the technical and educational skills of climbing instructors. Jon is the owner of Acadia Mountain Guides Climbing School. Like many full time guides, Jon also maintains a second career. He is a flight paramedic with LifeFlight of Maine. He has been a paramedic for 25 years and his emergency work resume includes working for the National Park Service as a backcountry climbing ranger in Rocky Mountain National Park as well as working in numerous urban and rural medical care systems.
