A model who founded a charity for kids with cancer has taken a six-year-old girl to the Caribbean so that she can take part in a 10-day dolphin therapy.

Katharina Stahn, 38, was voted one of the 100 German dream women by the magazine FHM in 2008 said she had always wanted to be a model, starting to pose in front of the mirror when she was just four years old.

Seventeen years later she became a professional model before moving into fashion and beauty with her own fashion label. She even has her own perfume line.

She also carries out a lot of social engagements on the side – including work with an association for kids with cancer called Children with Cancer in Need eV that she helped to found.

She said she was motivated because of a cancer case in her family and started the organisation in 2010 to give hope to others in a similar situation that includes financial support.

The organisation supports international children’s aid projects and also works with families, clinics and hospices to help with troubles, but also to offer opportunities to seriously sick children to have some of their dreams fulfilled.

That includes now the latest trip with 11-year-old Pia to attend the dolphin therapy course on the Dutch island of Curacao.

Pia has been getting treatment since being diagnosed with a malignant brain tumour four years ago, and after a 10-hour operation, 30 gruelling radiation treatments and months of chemotherapy she has been diagnosed as cancer free.

However the third position is needed because she has struggled to remember things since the operation and also has coordination problems, and the therapy has reportedly been proven to help.

Katharina said: “The therapy is working well. Whenever Pia frolics in the water with the dolphins, she is transformed.

“Before we travelled here, she forgot a lot very quickly, sometimes she didn’t even know what day of the week it was. It works much better now.”

Dolphin Assisted Therapy also known as DAT allows people suffering from mental or physical disorders to swim with dolphins as a form of treatment.
