DoctorSocks is real, but as far as my investigation went, appears to have been put on enforced leave of some kind. Personally, I favour the "Doc on the Rocks" hypothesis, a breakdown of some sort. I backed off the investigation once mental illness became an aspect, but I could rekindle my contact with various SF clinics.
Interesting - sounds very plasuible from what I've uncovered. I know who you are hinting at, but may I impertinently ask (pm would be fine), did you find anything that *positively* identified him to be that particular person? I've seen posts where Drsocks mentioned said person, and also ones where he used said person's name as his online identity.. But that still leaves the (slim) possibility that he is simply pointing readers AT that identity as part of his games.
So I'm wondering if anyone has directly contacted said person to get the confirmation, or verified it in some other way...?
Of course, if he ISN'T said person, then said person needs to be fully informed and take whatever action he sees fit..
Ummm.. did all that make any sense? 
Yes, that made sense. I googled the person in question and noticed something interesting. There were three or four pages of internet "yellow pages" listings, then practically nothing. No photo of him and his wife at the Opera's Black & White ball. No announcement that he had been named a trustee at his church. No angry letter to an editor about the rising cost of malpractice insurance. No speech at the rotary club. No daughter being named class valedictorian. No Facebook photo of him at a friend's wedding. Doctors lead carefully managed social lives; they are expected to be "pillars of the community." Outside of playing jazz in his brother's basement, the doctor in question appears to have
no social life. (Try googling your own doctor, you'll see immediately what I'm talking about. Mine is prominent in MoveOn.org!)
Oddly, in the one instance of charitable giving I found, he was referred to as "Pat T----," not "Patrick," and no title. Medicine is a discreet profession, fellow doctors tend not to publicize the faults and failures of their colleagues. He may be going through a "rough patch," but has not had his certification pulled. This is speculation, of course.
