Tedesco says his reasoning for stepping down is so he can spend more time on school board issues.
He is currently focused on two new committees on the board - one to sort out how neighborhood schools should work and another to make sure economically disadvantaged students don't get lost in the shuffle.
"A lot of people think maybe the new student assignment model may not serve our most vulnerable children," Tedesco said. "It was very intentional to have me lead both of those to ensure that there is no gap and that will take a lot of time."
However, there are some who may speculate on his departure based on statements Tedesco himself made - stating that some Big Brothers Big Sisters donors, who don't like or agree with Tedesco's school board positions, had threatened to stop giving to the non-profit group.
Tedesco says there were a few donors who expressed unhappiness with his roll on the school board, but says that had no influence on his decision.
"There were just a couple people who made some sentiments to that regard earlier on, but no, no, no that had nothing to do with my decision with this and this was my decision," Tedesco said.
The chairman of Big Brothers Big Sisters also says it was Tedesco's decision and he will be missed.
Tedesco says his responsibilities on the school board just require more time than he is able to give and by him stepping down from his day job, it will change that.
"The relationships and public buy in will all take a lot of time and I think particularly the early go, the first three months of that will take a lot of dedication and service," Tedesco said.
Meanwhile, Tedesco says he will be living mostly off his savings, while he focuses on the school board. He says the mission means more than money to him.
"If I have to sacrifice some of my personal resources, whether that's through savings now or whatever it takes over the next few months, I'm willing to make that sacrifice," Tedesco said.
Tedesco says he's going to devote the next three months to school board issues and then see where it goes from there.
