Nice job Pete of getting all the basic information out there!
http://www.oralcancerfoundation.org/resources/index.htm this link is all the resources in addition to the sections that Pete mentions in his posts, and there is one called NCI designated cancer centers, which certainly adds to their credibility, and an independent list updated each year from US News and World Reports called "NORC - best hospitals" which lists the top fifty cancer centers in the US from 1-50. Like Pete has said, a "team" is way better than a single individual in deciding what's what.
