Your friend is entitled to a copy of *all* of her records for her own reference.
She should have them anyway.
She needs to go to the crummy doc's office *in person* and request copies of those records from the front desk.
Then she can take them with her to any doc she chooses to consult.
Of COURSE she's seeking other opinions (doctor shopping?? WTH is THAT phrase coming from??? Sounds like a great idea to me, considering how many of them are incompetent), which is none of the dam doc's business at all.. That's what you're *supposed* to do when the current doc is unsatisfactory.
Report the crummy doc to the AMA, as DQ suggests below. Including whether the crummy doc balks at giving her copies of her own records.
