Willem Visser is a craniosacral therapist from the Netherlands, currently living in Portland, OR, USA. When he was young, he witnessed two grandparents from both sides of family suffering with Parkinson's disease. Finishing his study as a craniosacral therapist, he wrote a thesis on the work of biomedical engineer Aubrey de Grey. De Grey is known for his view medical technology can prevent human beings from dying from aging, including Parkinson's. Willem researched if and how craniosacral therapy could help with De Grey's proposed strategies. And of course also how De Grey ideas could help PD's. On his blog Willem later wrote about why craniosacral therapy can be of great benefit for Parkinson's. Willem Visser practices and teaches Craniosacral Therapy and Reiki. He also writes about Craniosacral therapy on his blog http://energyisflowing.nl/eng/blog/.
