School Reform Commissioner Martin Bednarek said Vallas' "biggest downfall" had been trying to please everyone.
"He has a hard time saying no to people. He promised people a lot of things."
Vallas acknowledged: "I promise more than I can deliver, absolutely. . . . If I promise 10 things and deliver six or seven, I'm still ahead of the guy who promises two things and delivers one."
Last week, he visited Dobbins Vocational-Technical High School, which was supposed to be completely repainted inside. Three of six floors had been. A distressed Vallas called maintenance and ordered that the job be finished.
