Some Seneca Valley students are welcoming a new principal to their school.
The school board approved the promotion of Erin Mazer from Seneca Valley Intermediate High School assistant principal to principal of the Haine Middle School during a meeting earlier this week.
This position became available when former principal Cassandra Doggrell was hired for an administrative position within the Upper St. Clair School District.
Mazer is a Cranberry Township resident and has been with Seneca Valley for the past two years.
