Principal Already Gone After Only Two Years

Hi there, I graduated from Prep in the early 2000s. I noticed the other day that the school is already looking for a new principal. The guy they hired, Bill Gotch, only lasted two years. He was hired after the principal prior to him, Jim Bopp, left after six years to take the same job at Brophy Prep in Phoenix. I'm used to when John Naatz had the role forever, so this high amount of turnover for the role is a bit concerning. Does anyone know why Prep suddenly is struggling to hold onto principals?
