New York has some of the best facilities in the country. Memorial Sloan-Kettering has an outstanding reputation http://www.mskcc.org/locations
If I lived where you are, that would be my first choice.
What influenced our choice, as I'm a caregiver for my dad, was location, a good and friendly doctor, and a reasonably good facility. In dad's situation, the treatment is chemotherapy only, and weekly visits. So choosing a local facility made it easier on him.
Best wishes, and good health to you.
