“What I am most proud of in my time leading in DPS is where I chose to lead,” Nick wrote in his letter sharing his decision. “DPS giving me the chance to go home and make some things right by the students there is a gift I will always be thankful for.”
DPS officials said they would be announcing an interim principal early next week.
