I had the exact opposite experience I can guarantee that. Once Dr Epstein left JHU (just as I was sending slides) the biopsy report for me was just a few scant lines with no physician name (probably somebody in training but no apparent supervision since Epstein was gone). This was last year. The Mayo/Rochester one was super professional and very detailed. JHU even mixed my paperwork up, multiple calls resulted in nothing. I felt it was just a money making effort done by somebody unsupervised + untrained and poorly done completely, plus with the paperwork mix up I even call into question their entire practices. Perhaps JHU has picked up since, but to be honest I would never send another thing to them, and I am a JHU graduate.
