Maarten was born and raised in The Netherlands, allowing him to explore Europe through backpacking and bike touring. At the age of 18, he moved to Ontario with his family to enjoy Canada’s natural wonders and embark on a new adventure. 

Since moving to the Bow Valley in 2013, Maarten has been working through the ACMG program towards his IFMGA Mountain Guide certification. He is currently certified as an ACMG Alpine Guide and enjoys guiding ice and mixed climbing throughout Alberta and British Columbia.  


Maarten lives in Exshaw in the Bow Valley with his wife Lin and their cat Am. He has pursued ice and mixed climbing throughout North America, usually going for long walks to seek out new climbs. His travels have taken him beyond Alberta and British Columbia, to Quebec, Alaska, Morocco and Iceland.
