My dad had a doctor, either Bonebreak or Breakbone, in Chicago. Gotta be related.
We had a dentist up the street named Dr. Gore and my ophthalmologist’s name was Dr. Light.
I once typeset a list of doctors affiliated with a local hospital. The only one I can remember is Dr. Ow.
I was over at a friends house one day, and I noticed a business card sitting on their kitchen table. It was for an OB-GYN named Dr. John Holmes.
I kid you not.
I said “You’re pretty gutsy letting your wife go to him.” He had no idea what I was talking about.
My parents went to med school with a guy who had a rather unfortunate last name. Upon graduation, he was able to begin introducing himself as…
Dr. De’ath
FWIW, it’s pronounced Deeth, but it’s still alarming to read.
Of course, my father’s last name means “Butcher” in our native tongue, so it’s probably a good thing he decided against a career as a surgeon. 
I used to go to a neurologist and headache specialist named Dr. Megahed.
I wouldn’t want to be in the waiting room of Dr. Godot. I’ve lookede through listings of MDs, and havenb’t been able to find one, though. Probably just as well.
It woul also be awful to be Dr. Einstein. There already are scientist with that name, who must take an awful lot of ribbing.
A quick search turns up several Dr. Moreaus, including one unfortunately named veterinarian in Marksville, LA, and a clinic that must’ve been named tongue-in-cheek in Albany.
One teaches at my alma mater. He always had a reputation as a great guy. I think he’s a great-nephew or something.
There was a Dr. Slaughter here too, but I think he was an oral surgeon.
Flipping through the yellow pages, I see:
Dr. Kreul
Dr. Gross
Dr. Hecox (renal)
Dr. Loos (urology)
Dr. Poisson (I know the word, but the average American probably doesn’t.)
Dr. Savage
I saw a podiatrist in the DC area named Dr. Korn.
Father and son dentists…last name of Toothman.
I’ve seen a Dr. Look (a dentist, sadly) and my SO’s been to Dr. Rad.
My first optometrist was Dr. Glasser.
The obstetrician who attended my birth was Dr. Catcher
I went to a walk-in clinic for a UTI once and was treated by Dr. Burns.
The doctor my husband consulted about a vasectomy was named Rod Crocker. We giggled.
Years ago I saw a sign in a small Vermont town (I think it was Randolph, but forget) that had a sign outside an office that read:
Doctor
Mechanic
Dentist
The pediatrician my sister and I both went to as kids was Dr. Paine. Very nice lady.
There’s a doctor near where I grew up named “Tribble”. I always wanted to see him on “The Peoples’ Court” just so they could announce the case as “The Trouble With Tribble”.
The doctor who did the procedure had a mundane name, but the machine that he used to cauterize my plantar wart had the prominently-featured brand name of Butcher.
There’s an OB here by the name of Dr Elvis Seman.
Not quite what the OP was looking for, but in the town I grew up, there is a dentist whose sign reads “B. J. Rippy D.D.S” and my ex once pointed out "every time I drive by that place, I think “blow job rippy, dirty dick sucker!” I still can’t drive by the place without a fit of giggles!
I was once treated by a Dr. Paladin, as a child. Yeah, being able to heal people by laying on hands is probably pretty useful in that profession.
I don’t get it.
