Congrats on your first appointment, and I'm sorry to hear about the tragedy in your village.
Now... 7 months to get in to CHX? In my experience - and the experience of many others here - that's
very optimistic. Not only could the wait for your first appointment be much longer than that, but the gaps between subsequent appointments can also be very long.
I haven't used Dr Curtis myself, but like you I have read positive and negative stories. I prefer to reserve judgement because I've never met him.
Another one you might want to research is Dr Stuart Lorimer, who is one of the doctors at Charing Cross but also runs his own private practice in London. I've only had limited dealings with him but I found him pretty helpful. I'm going the NHS route myself.
