hi, rachael. as others have stated, you can't really go wrong with either team; i feel it really - when you're choosing between the two - comes down to your gut.
as our resident young dancer has weighed in on friedman/giannotta, i'll go ahead and complicate things for you further (
) by acknowledging that my son had a great result with drs. schwartz and miller at house, in february. you might also use the search function to look for references to giannotta and schwartz, if you're interested in finding others' experiences; i know that was tremendously helpful to us, when we were weighing our options.
but, you really can't go wrong. i'd urge you to return dr. brackmann's call to get feedback there too, just so you can make a fully informed decision, but either way, you'll be in great hands. i wish you the best with your journey and hope you keep us updated.
(of note, sheren's tumor, my son's, and yours, are all in the same size range (high-medium/large), so it's an unusually level playing field when considering these two teams.)
