A bit late to the party, but I've just seen Dr Curtis myself and was impressed by him. He was likeable and thorough; he seemed quite serious and saw us about an hour early, probably because we were larking about in his waiting room. Ahem. So I apologise for being unruly.

In my case, the necessity of seeing him is that I've had a lot of difficulty with CX GIC referring me for surgery, with Barrett and Lenihan dragging their feet at every opportunity, even though I'm at almost three years' worth of RLE. It seems to come from Barrett not really believing agoraphobia is a thing and that I should basically pull myself together otherwise I'm not worth referring (not his exact words, though he's hardly been understanding or sympathetic about it).
AFAIK he's still refusing to sign my referral; Dr Lorimer managed to get Lenihan to countersign it, which was obviously big of her considering she's only my lead clinician, but apparently she's done so on the pretext that any referral with her name on it is not used to actually have surgery, which I find frankly bizarre. And though I should've been discharged from CX following my referral, Barrett has insisted I make another appointment with him next year so that he can continue to interfere. It's been a really awful year.
So I'm doing what I should have done in the first place and switching to the private route: fortunately Drs Curtis and Perring (just around the corner from Dr Curtis' office) seem very approachable and conscientious. I just wish I'd done this a couple of years ago and saved myself a great deal of trauma.
