Hi Michele, I know traveling around the city is difficult and can be an issue if you are not feeling well. BUT we are very lucky to be so near to Sloan.
They do have some centers outside of NYC. I know there are some on LI . Not sure of location or speciality but it might be worth looking up. I think their surgeries are all still done in the city but evaluations, follow-up care.etc are done at some of their sites off the main campus.
