First, I read another of your threads that claims that your SON has a “perfect GPA” of 4.2, unweighted. It is impossible to have 4.2 GPA that is unweighted unless you are on the 5.0 system in which case his GPA is not perfect.
And just because a school isn’t Harvard doesn’t mean he can’t get a fabulous education there. Especially if he wants to continue to grad school or medical school. You don’t even know that he’ll get into Harvard. Is he a NMF? What is his REAL GPA? What are his test scores? What subject tests has he taken? What makes his goals unique? Plenty of other top notch kids apply to these schools who have spectacular grades and scores and do sports. If there was more information, maybe the commenters could help you come up with alternatives with Harvard as a reach school. Because regardless of your son’s accomplishments, it’s always a reach unless he has done something extraoridinary.
