DOUGLAS COUNTY, Colo. (CBS4) – Two principals with the Douglas County School District are no longer leading their schools.

Ally Berggren, the principal of Buffalo Ridge Elementary, and Alan McQueen, the principal of Heritage Elementary, were both let go.

Parents received a letter that didn’t say much or give specifics, but made it clear come Monday students would have a new principal.

According to the Heritage Elementary website, McQueen had been the principal at the school since 2009.

“It is my unfortunate responsibility to inform you that Alan McQueen will no longer serve as the principal at Heritage Elementary due to the violation of Douglas County School District policy regarding substance abuse,” the letter stated.

It came the same day Berggren resigned for the same reason. The district told parents that Berggren had violated substance abuse policies and is “currently receiving treatment with support from the district.”

It’s not clear exactly what each person did, but the district’s drug policy says employees can’t possess or be under the influence of drugs or alcohol on district property, at a school sponsored event, or on the way to work.

Both have asked for privacy.

Several parents had nothing but great things to say about McQueen. They also stressed that it is a great school and its record speaks for itself.
