Anyone heard of Dr Damien Downing?

[Wombat140]

Amy Smith of California has recommended us this ecological medicine doctor in London, Dr Damien Downing, who she says is "brilliant" but I can't find anything on his website about PANS, and a web search on his name and "PANS" or "PANDAS" turned up nothing, though he does seem to have done a lot on autism but mostly talking about heavy metals and vitamins. Has anyone been to him or heard anything about him? I did come across a few mentions of him on forums and things while I was doing the search, all from people saying they'd got no better or got worse while seeing him.
