Sandra J. Theunick has been named head of school at St. Andrew's Priory School after acting as interim head for more than six months at the Downtown private school for girls.

"We believe she is a great asset to our school," said Ivan Lui-Kwan, chairman of the school's board of trustees. "Sandy is not only highly experienced as a Head of School nationally, but she brings strong leadership skills and a deep understanding of the global learning environment and the diversity of students we serve."

Theunick has more than 26 years of experience as a head of school for schools around the nation, the school said in a news release.

She has been Head at The Seven Hills School in Cincinnati, the Chapin School in New York City and at schools in New Jersey and Washington, the Priory said.

She has a Master's degree in divinity from Washington Theological Union and a BA in psychology from Newton College.
