International Team

The International Team has three main objectives:

  • To support the 19 National Organizations by providing leadership and training
  • To publicize the work at an international level
  • To foster the emergence of new A Rocha initiatives

ARI does not have a permanent headquarters: the team members live in eight countries, sustaining their relationships by meeting all together twice a year and as necessary in sub-groups, taking advantage of online conference calls to cut down travel. The Directors meet regularly in Oxford, UK.

Founders: Peter and Miranda Harris

Peter and Miranda founded A Rocha in 1983 and now share responsibility for shaping the organization's vision and ethos globally. More
