The Northeast has never been a Mecca for ME/CFS patients. Susan Levine is the only specialist left in New York City. Two others - Richard Powell and Derek Enlander - have retired. Otherwise, NY is a wasteland full of God-complex medical specialists who don’t know or care about ME/CFS or any related illnesses (Dysautonomia,MCAS) who treat you like you are invisible or worse.
Susan Levine is very kind, but because she accepts insurance and is the only CFS specialist left in the New York area, she has a very busy practice with a heavy patient load. She is also involved in research, which is another claim on her time. When I go to see her, I find it is best to prepare with specific questions and to ask about treatments I have read about through my own research. She may agree to prescribe the treatment, recommend further testing first, or explain why she thinks the treatment is a bad idea. But office appointments, especially follow-up appointments, are somewhat time limited, so if you are coming a long distance to see her, you may be a bit disappointed that she can’t spend hours on end talking to you.
In Boston, David Systrom has some expertise in ME/CFS, but seems more interested in research than soup-to-nuts treatment. I have seen him and wouldn’t make him my primary ME doctor, as he is only interested in treating some aspects of ME/CFS and also has a very high volume practice.
If traveling and wait lists were non-issues, I would probably head to CA to see David Kaufman, as he does seem focused on deep dive investigations and uses every treatment available, up to and including IVIG and Rituxan. Be aware, however, that “aggressive” treatments sometimes backfire. Even with the best intentions, some doctors will make some patients more sick. (To wit, Kenny DeMeirleir at one time was regarded on this forum as a stellar ME/CFS specialist...he is now viewed mostly with disdain, apparently from overprescribing antibiotics.)
