The team of Welttierschutzgesellschaft e.V.

Our vision is a world in which animals are perceived by humans as well as being treated animal friendly and with respect. The following people support this:


Katharina Kohn

Director Katharina Kohn brings the different projects together and ensuring that resources are used in the best possible way. The fundraising expert had previously been responsible for the funds acquisition of the association. Therefore, it remains very important to her to maintain the high degree of transparency.

For Katharina Kohn, animal welfare also means „taking responsibility“, because if everyone contributes only a small part, we can all together improve the world for the animals.

Donor service and -management

Anja Zieke

Head of Donor Management
In her childhood, Anja Zieke spent many weekends on her grandparents’ farm. Her enthusiasm for animals that developed there persisted and today she is not only a passionate dog owner, but also works with Welttierschutzgesellschaft to help animals worldwide:
As Head of Donor Management, she is responsible for database and address and payment management. She is also the contact person for all matters relating to inheritance and bequests, monetary donations and donations from companies and foundations..

Katharina Felsenstein

Donor Support and Fundraising
„In my next life, I will be an elephant“ says Katharina Felsenstein. She is an absolute elephant fan and became aware of us in autumn 2014 through our Sumatra project.
Through her years of experience -for example in publishing, sales and customer service as well as film promotion -, she is particularly ambitious in supporting the areas of donor support and fundraising.

Lili Wunderling

Donor Support

As a child, Lili Wunderling spent a lot of time with animals on her grandparents‘ farm. After graduating from high school, she did volunteer work, including caring for strays in Ecuador. On her travels, she discovered her interest in development cooperation.

In addition to studying „Sustainable Development Studies“ in Göttingen, she now supports Welttierschutzgesellschaft’s donor support with advice and practical help.

Communications and Fundraising

Wiebke Plasse

Head of Communications and Fundraising

Whether as a freelance journalist or as a volunteer: Wiebke Plasse’s wish is to contribute to a better world on many levels. Issues that are too often underrepresented in society are particularly close to her heart.

After studying journalism and working as a freelance journalist for several years, during which she increasingly devoted herself to nature and animal welfare issues, she joined Welttierschutzgesellschaft in 2015 in the area of ​​online fundraising and marketing.
Since 2018, she has headed the communications team and is responsible for the areas of communications, fundraising and campaigns.

Christoph May

Press and Public Relations
Millions of migratory birds, which are hunted annually in the Mediterranean region, brought Christoph May on the topic of bird protection – and a little later to animal welfare in general. His major concern is to awaken a broad interest for the needs of animals.
He implements this at Welttierschutzgesellschaft in the field of press and public relations and can draw on several years of experience in this area.

Marie Walther

Since her childhood, Marie Walther has considered animals and humans to be equal and the relationship with animals to be something special.
As a cook and in publishing, she has primarily dealt with this relationship within consumer behavior and eating habits. This led her to the desire to actively work on encouraging people to behave more consciously towards their fellow beings. After completing her Master’s in Applied Literature, she is now finally using her passion for text and animals for her heart’s topic and is communicating this in fundraising at the Welttierschutzgesellschaft.

Line Sebert

Communications Intern

Line Sebert has been passionate about animals since she was a child and was already doing volunteer work at an animal shelter when she was young. As part of a mandatory internship during her studies of „Public and Nonprofit Management“, Line Sebert joined Welttierschutzgesellschaft, where she wanted to gain a deeper insight into the work in the animal welfare sector. After completing her studies, she hopes to devote herself to the professional protection of animals. During her internship, she is actively supporting the areas of communication and campaigns.
