Numero Una! Meet Our New Head of School.

Chris Young ’90, Board President: “The Board of Trustees is excited to announce that Una MacCarthy has been unanimously selected to become the next Head of School at The Lexington School. Una has been a dedicated leader at TLS since 1996 and is well prepared for this next step in her career. 

The process for selecting our next Head of School began in July with the formation of the Search Committee composed of seven current TLS Board Members. The search firm RG175 was hired to conduct a national search which attracted more than a hundred applications. RG175 narrowed this incredibly strong pool down to ten semi-finalists who visited the TLS campus for interviews with the Search Committee. From those ten, the Search Committee selected the three finalists whom you have met over the past two weeks. It should be noted that Una was the only semi-finalist candidate to receive the highest ranking from all Search Committee members.”

There are twenty plus years of TLS families and friends who know and love her. That leaves a few more decades of TLS families and friends who may not know how lucky we are. If you don’t know her already, you must MEET UNA:

It’s pretty easy to see how she got here. Una grew up the third of four girls in small town, Glasgow, Kentucky where the community is close and comfortable.  A love of the great outdoors took Una every summer as a kid to Rockbrook Camp in North Carolina, camper, counselor, and eventually Director of summer programs. Red-headed adventurer that she was, Una took the risk in high school and left Glasgow to attend The Masters School in Dobbs, MA where she found her love of independent education.

Community, the great outdoors, and independent school education are at Una MacCarthy’s core, directly impacting the path she chose for her life’s work. She completed her BA in English at the University of Kentucky and went straight into teaching middle schoolers at Hammond School in South Carolina. A few years in, she finished her Masters in Educational Administration at The University of South Carolina and became Middle School Head. Una has never waivered on where and what she wanted to be–in school or outside of school with faculty and kids.

In 1996, Una was asked to join The Lexington School, and she’s been home ever since. Una has been involved in all aspects of The Lexington School’s leadership. As Middle School Head and Assistant Head of School, she is advisor to the Head of School and lead Division Head. As such, Una has been an integral part of all strategic planning initiatives, school task forces and committees, and she is a strong implementer of resulting change.

Una: “Twenty-two years of love for this school has allowed me the opportunity to build an incomparable portfolio of administrative experiences. Collaborating with an incredible team of professionals, I am proud to be a part of this nationally-ranked school. We have come a long way. I understand the significance of transition, the need for stability, and the boldness needed to continue moving forward.”

For Una, The Lexington School is family–quite literally. She is married Lexington School alum, Reid Freeman ’73, three of her four children (Hart Freeman, Katherine Freeman ’04, Justin Freeman ’16, and George Freeman ’19) have attended TLS, and she has long-standing and deep relationships with generations of TLS alums and their parents.

Una: “I love what I do because I believe in what I do. I am passionate about TLS because year after year I have seen the power of its influence in the lives of the children who walk these halls. I am energized and enthusiastic to continue the good work that is part of the history of The Lexington School.”

Una will (officially) begin her work as Head of School on July 1, 2019. A seamless transition, she will serve as cultural custodian and momentum maintainer of this wonderful school community.
