The team of WTS

Executive board

Karin Siegmund

The Director of WTS has been committed to a sustainable development and the protection of our natural resources for many years, within international NGOs as well as directly on the ground. “Animal Welfare asks us urgent ethical questions. How can we develop a better understanding for our fellow beings and how can we improve our actions? There are a lot of good examples that we can learn from.”

Academic Education and CPD

Dr. Wendy Phillips

Senior Manager Program VETS UNITED
The passion for animals is a recurring theme in Dr. Phillips’ life: Started with a study of veterinary medicine, her first job as a veterinarian brought her to a center for injured and/ or confiscated wildlife. She continued as a veterinary conduit in free castration clinics, vaccinations and veterinary treatments for domestic animals and livestock in Africa and a little later for stray cats and dogs in Thailand. Today she heads our program VETS UNITED.

Carolin Breitenbach

Junior Manager Program VETS UNITED
Since her studies of veterinary medicine, Carolin Breitenbach is fascinated by the connections between human, animal and environmental health. Her experiences as a veterinary practitioner in South America and Germany made her realize that a sustainable improvement of animal welfare can only be achieved by involving local communities. At WTG she supported the implementation of this approach, by coordinating stray animal projects. After joining the WTS, she now supports our program VETS UNITED which promotes education and training for veterinary professionals e.g. in Africa.

Future Concepts

Katharina Tölle

There she was responsible for campaigns and put a spotlight on dairy cow keeping, promoting a dairy guidebook, field checks and a farmer’s list for consumers. After joining WTS the sociologist commits herself as a program manager to the important issue of animal welfare in development cooperation.
