Peter Rijhnen

peterPETER RIJHNEN– Manager

Peter and his partner arrived 8 years ago in NZ. Soon after his arrival he accepted a role as a (registered) AOD counsellor in a Drug Treatment Unit (DTU) in the Christchurch Men’s prison. His leadership and managerial skills were acknowledged by his management and he was promoted to the role of Clinical Manager in the Hawkes Bay Prison. This lead to a further promotion to National Programme Manager of 10 Prison based DTU’s. Although Peter was enjoying his new role, the once-in-a-lifetime opportunity to manage a Residential Treatment Centre such as St Marks, was irresistible.

In the Netherlands Peter has been working in different roles for the Outward Bound School (OBS), as Instructor/Trainer and Manager. In these roles he worked in collaboration with the Dutch equivalent of Work and Income, CADS and large corporations. Furthermore, he worked as a Physical Education Tutor at a training institution. The different roles naturally evolved into his own Bureau for Management Training and Education. Peter still provides training and education for management of International businesses as time permits.

Peter’s passion is all about people and supporting them to become the best they can be. He supports individuals and teams, clients and colleagues, volunteers and staff with the same enthusiasm. He combines his knowledge, skills and focus to encourage others to connect and work together because he believes that working together gets the best result for all people involved.
