Know-How Exchange : Taglines/Names

I work for a non-denominational Christian school that serves grades PreK3-12. Our current tag line is "a Christ-centered college preparatory school" (which one of our competitors also started using--actually, lots of schools use a similar line and we wish to break away from the pack).

The statement is true, although we feel it does not encompass all we. Our curriculum, test scores, etc. are top-notch, the Christian values are enfused through each level of the school, but where we truly 'blow everyone else away' is on the environment, which seems difficult to put into words. People comment on how loving and nurturing our teachers are, and how great (nice) the students are. How do we incorporate that into our brand statement/tag line? Any ideas would be appreciated.
