Dr. Kennedy is most famous but you would probbaly not be able to see him as ha
has cut back his load.

But it is one of the very best centers of excellence in sinus surgery there is
anywhere and there are quite a few famous surgeons there.

I went.  didnt get to see dr Kennedy.  saw a dr. Chui.  I'm sure these guys
are good but i think i spent about 5 minutes with the dr. and got nowhere.
he looked at my yr old cat scan - stuck the scope in my nose and told me to
get together with an allergist, as my primary concern is persistent,
unrelenting nasal drip(or something).  he didnt think that there was
anything that he could surgically do for me (i wasnt asking that
specifically) that hadnt already been attempted with 2 previous surgeries.
he thought that the hole that i had in my septum could not be repaired and
that it was not the cause of my primary problem.  I was unhappy with the
visit, i had expected to get more tests - (like for AFS) but was rushed on
out of there.  i imagine that many will see this and think that i must be a
hypochondriac, which i never fully dismissed (although several other
surgeons did) but whatever i do have actual physical measurable symptoms.
i do intend to see an allergist/immunologist/whatever again even though i
had spent a yr on shots with no noticable improvement.  all symptoms are
different though and maybe you will find value in the UofP visit.  good
luck.
