He’s a deadly combination of arrogance and insecurity.
A comment about the relatively new director of admission and financial aid at a well known prep school made by another person in the field. The school has seen a precipitous drop in the academic quality of incoming students under the new director, who is also single-handedly scuttling what was a top prep school athletic program. He dismisses any input from, or meaningful communication with, others at the school who want to fix the problem, telling them he’s the only one who could possibly understand what’s going on. A classic example of the Wizard of Oz mentality.
