So off hand, my reaction to your profile is it is very STEM heavy and not so much HASS. People have been discussing the issue of you maybe getting up to three years of History/Social Studies, which would help a bit but I think still leave you quite STEM focused.
That’s perfectly fine but kids like that from our feederish HS tend to have the best luck with colleges that are similarly more STEM-focused. Like, to me, a lot of your Ivies do not seem like a natural fit, so I would consider trimming those. Stanford and maybe Princeton you could leave, but I would maybe consider dropping Yale, Harvard, Penn, Columbia, and Brown, as well as Northwestern, but maybe adding Cornell (assuming you bump History/SS up to three). I think that would still be six private Reaches in addition to the UCs, which is probably still too many if anything.
OK, then you have all these midsize private universities for Reaches, but none as Targets or Likelies. Part of that may be you like your UC schools, which is fine, but usually the STEM-heavy kids in our HS also take a look at privates like RPI, Case Western, Rochester, and so on–all of which offer merit, and although I know you said cost isn’t a factor, it doesn’t hurt.
