Each ORG has a specific area where they seem to function best. I see no single ORG having the staff or ability to deal with all the needs of the PD community while still pushing for better treatments and a cure. The best solution is to have them all talking to each other and leveraging the strengths of each. Of course we have to continue to each be advocates least they forget why they exist.
The best we can hope for is some type of formal strategic alliance between them or some way to manage each ORGs best assest(s).
