Guides & Staffing

Tangent Expeditions employs several year-round staff together with a seasonal team of snowmobile guides, boat drivers and mountain guides. These are some of the people who will be looking after you in Greenland.

The qualifications held by our mountain guides are:

Mountaineering Instructor Certificate (MIC) - the highest level of award available in British mountaineering.
IFMGA Mountain Guide – the highest qualification in mountaineering, held by the most qualified and experienced professionals to lead people in the mountains, with a training and assessment that takes many years and exceptional skills to achieve.

All our guides are trained in outdoor mountain first aid.
