Our People

Since our small beginnings over 30 years ago, the HALO family has grown to employ 11,000 staff around the world.

In the countries where we work, we become part of the local community, training and employing men and women from the communities we serve. We create jobs in places where opportunities are often scarce and our local staff make up 98 per cent of our total workforce. Visit our individual country pages to meet some of our local and international staff or view the profiles below for HALO executives.

Our headquarters are in the beautiful Scottish hills of Dumfries and Galloway. We also have offices in Salisbury, UK, and across the Atlantic in Washington DC.

"HALO is committed to making the world a safe place. We clear mines to stop people from being killed and wounded. We restore land for farming and other livelihoods and we restore confidence in countries devastated by war. I am proud of HALO's men and women, many of whom come from villages and towns living with landmines, who work everyday in pursuit of this goal."
