This was quite an old post, so the member may well not be on here any more. You could try clicking on their avatar & send them a private message; did you ever try that after you posted before to ask about this doctor? I’ve done a quick search of the past discussions, there doesn’t seem to be any more recent mentions of Dr Snyderman unfortunately!
I’ll post a link to the current doctors list, in case you want a second opinion:

Let us know how you get on with Dr Snyderman!
