"It is a great pleasure to work with Nina. She is persistent and focused on results whilst navigating complex organisational and interpersonal systems. Doing a project with Nina means you will get it done with high quality and on time."

Barbara Weber
Programme Director, Amnesty International

"Having worked with Nina over the past two years I have experienced at least three occasions where her insights and skills as a learning practitioner helped build trust and a strong basis for future collaboration among diverse group. From the rigorous and inspired preparation, charismatic delivery and thorough evaluation, all the experiences in working with her were highly professional, efficient and inspiring; her sensitivity, passion and hard work are remarkable and I can highly recommend working with her for team, idea and project development."

Marina Barbalata
Programme Director Greenpeace in Central and Eastern Europe

"Nina helped us develop our strategy for implementing the SDGs in Austria. As part of a perfectly organized workshop, we managed to build the framework of our strategy within a day. The targeted and highly professional preparation and follow-up was one of the success factors. Nina found the right method for every question and adapted it flexibly to the situation. Her great campaigning experience was clearly noticeable in every situation which was of great use to us. ÖKOBÜRO will continue to work with Nina. I also recommend it to anyone facing similar challenges."

Thomas Alge
Managing director of Ökobüro, the Alliance of the Austrian Environmental Movement

"Through our team development workshops with Nina Thüllen we have not only increased the efficiency of our collaboration, but also brought our team spirit to a new level. Nina knows how to make the issues emerge, to recognise the needs and to adapt her workshops accordingly flexibly. She has become a valued companion for the entire team with her calm, clear and competent manner, whose impetus always help us. Thank you!"
