@sue6408 My understanding is that Mayo has a really good program for C. Diff. You should check that out. An on line journal called CONTAGION LIVE has a set of videos in which national experts discuss specific C. Diff treatment issues. You could go to that video and get a sense of each of these doctors. Here are their names and locations as I wrote them down: Lawrence Brandt at Albert Einstein Hospital in NYC, Erik Dubberke at Washington School of Medicine in St. Louis MO, Peter Salgo at columbia University Hospital (i was less keen on him from the video), Yoav Golan at Tufts University in Boston, daniel Freedberg at Colunbia Presbyterian Hospital, NYC. The two doctors who i have seen and who seemed good to me are here in NYC. They are Harjat Singh (646-962-5666) , an infectious disease specialist (she know a lot about how C.diff works) and Carl Crawford, a GI with C. Diff specialty (646-962-4000). You could check out all these doctors on line and go to whichever one is closest to you. There is a wait to get in. If you can't find the videos let me know.Good luck, Anna
