I can only speak regarding ASD, but their extra-curricular program (at the high school level) includes:  baseball, softball, basketball, soccer, cross-country, swimming, badminton, forensics, musical programs (both instrumental and vocal), drama, art of all types and more. 

Academically, it's a very strong college prep school.  This year, graduates were accepted to Princeton, Harvard, Dartmouth, Rice, Purdue, Pepperdine, Duke and more. 

My son just wrapped up his middle school years there and I couldn't be happier with their programs.
