Honorary Ambassadors 

They carry the NG idea out into the world: honorary ambassadors for Nehemiah Gateway. 

Siw and Matthias Schindler

In 2010, police officer Matthias was diagnosed with incomplete paraplegia. His journey out of the wheelchair brought Matthias to cycling, and today he holds, among others, multiple world championships in paracycling (time trial), the World Cup, and he won a Paralympics bronze medal in Tokyo 2020!

Through all his challenges - severe disability, career break, professional sports, world class competition – his wife Siw always remained by his side. Their experiences and last but not least their strong trust in God enable Siw and Matthias to support other people in overcoming seemingly impossible obstacles and to show the way to lead an active, healthy and successful life despite a physical disability.
