Tierney takes over as of July 1

The Tatnall School Board of Trustees announced the appointment of Charles A. Tierney III as the school's ninth Head of School to succeed Dr. Eric G. Ruoss, who is retiring at the end of the 2013-2014 academic year.

Tierney, who will start at Tatnall on July 1, is currently the assistant head of school at Northfield Mount Hermon in Mount Hermon, Mass. During his 16-year tenure, he has been responsible for curriculum development, fundraising initiatives, faculty oversight, and management of a STEM building task force. In addition, he recently served as Interim Head of School, with responsibility for the day-to-day operations of the school, including managing its $30 million annual operating budget and overseeing its $3.4 million annual fund.

Tierney received his master's in education from Columbia University as a Klingenstein Fellow and bachelor's degree in history from Dartmouth College.

"Charlie will bring an impressive array of talents and values to campus, as well as an energy that is infectious," said Kathryn Fischer, president of Tatnall's Board of Trustees. "His passion for education, exceptional management experience, strategically-focused vision and integrity made him a unanimous choice for the position. As a result of our extensive nationwide search, the Tatnall community can be confident that under his guidance, our school will continue its rich tradition of academic excellence."

Prior to joining Northfield Mount Hermon in 1998, Tierney served as the director of studies for St. Stephen's School in Rome from 1996-98. He began his career in independent education as a history teacher at the Berkshire School from 1985-88 and also taught history at his alma mater, Choate Rosemary Hall, from 1988-1996.

"It is with wholehearted excitement, optimism and pride that I accept the role as The Tatnall School's ninth Head of School," said Tierney. "I am honored and humbled to lead and serve such an important learning community."
