Here's my two cents......
Koufman: Most ppl either love her or well not so much. She focuses more on lpr then gerd, yes she may be more open minded to listen or even agree with you. She does a couple test that alot of other's do not. In the end she will NOT offer you anything that any other dr can or will. There is no magic there, some feel her diet helps (don't need an appointment to buy the book), whether it's meds or surgery (she's not a surgeon) your treatment will not be different. Just a side note Koufman had nissen surgery for her own gerd, to me that's kind of like going to a bald barber.
Cleveland Clinic in Fla: Is this a Mayo clinic? Fla, does have some very good medical care. If it's a large medical center I can only assume it has very good dr's. I would look for more info. on the clinic.
Bottom line: That's a ton of money to spend, again pretty much all dr's treat gerd the same. There's several different meds they'll all try. Surgery, make sure you pick a VERY experienced surgeon (Koufman doesn't do surgery). Go to a top large medical center in Fla and make the most of the time with your mom! You get a two for one......money well spent!
