I would echo some of this. We are a Christian but not Catholic family, with a son who identifies as atheist, and think it's a very welcoming place. It is, however, a place that expects respect an thoughtfulness for religious belief, which we are also glad for. But it's definitely a place that emphasizes intellectual and spiritual commitments, and where you'd be expected to do the same or your son could have a hard time. That isn't to say that there aren't SAAS boys who are wonderful athletes, but it's definitely a place that expects the boys to prioritize schoolwork first.
