For so many years I just used my intuition and experience in managing them, until I met Wieke and I asked her to give my team and me useful insights into understanding people better by using a tool called “Global DISC”. Since then, the team have significantly improved their self confidence and leadership skills. – Retno Nartani, Director HSE Corporate Sinarmas Mining, Indonesia

We at Steel Blue have been doing business in Indonesia for close to 15 years and thought we understood Indonesian culture until we met Wieke. Wieke’s work with the Board of Directors and executive have opened our eyes in the way in which we communicate and reach agreement with our valued Indonesian business partners. Wieke’s professionalism in dealing with Steel Blue was most commendable and she was able to get her point across in a very effective manner. Publications and supporting material was again of a high standard, easy to read and very pragmatic. – Garry Johnson, former CEO, Steel Blue, Australia

Wieke is extremely knowledgeable on cross-cultural matters and has been a very valuable educator and mentor for me and others. Her knowledge and approach is relevant to a wide range of nations/cultures and the resulting cross-cultural interactions and issues. She is a very valuable go-to person in this vitally important area. – Rob Delane, Special Adviser Agribusiness Expansion, Department of State Development; The University of Western Australia
