Those considering using Dr Sandbach or recommending or referring anyone to her might well be advised to peruse the details and references to correspondence on this page.
A 17 Nov. 2014 update: The concern in consulting Dr Sandbach is that she might carry out a $115.00 test on you, with no subsidy from Medicare, which appears to have nothing to do with anything, and about which she feels absolutely no need to explain anything to you or anyone else for that matter – see this correspondence. One gets the impression that she has never ever felt accountable to anybody about anything.
