Wooden Hut
Expat, South-east asia

Before we got attached to IHM, it was like we were at a great distance as far as the health concerns of the sending organization towards expatriates go. Now it’s like, ‘this is a very important part of you, and we want to do everything that we can to help you.’ It went from just about nothing, to just about everything.

What People Say

Expat, South asia

IHM's re-entry care approach sought to nurture my ‘whole- being.’ The insightful and spiritually enriching feedback empowered me to move forward with new hope and new perspective.

Director of Member Care

You are a pioneer in the Canadian expatriate care field. Thank you for taking on the difficult task of introducing new ideas and following a vision, rather than staying with the comfortable familiar things in life

For over three decades, Duncan has been involved in expatriate care while residing in the U.K., S.E. Asia, the U.S.A. and now Canada. Having crossed multiple cultures with his wife and kids, Duncan is acutely aware of the diverse challenges facing expatriates.

As a sought after speaker, Duncan accepts invitations to present plenary sessions, conduct workshops and facilitate retreats on expatriate care and development at different locations throughout North America and globally.
