In July 1995, Chris Elliot became Head of School. Under Elliot's leadership, student council was re-established and the tradition of year-long themes was adopted. The theme for 2021-2022 is Friendship. The 90's debuted such traditions as the two-mile Apple Pie Run, and the introduction of a school mascot, the Tenacre Tiger. The new millennium ushered in big changes for Tenacre. Following a capital campaign, the school opened its doors in September 2000 to a new gymnasium, library, multi-media center, sixth grade classroom, courtyard and administrative offices.
Tenacre celebrated its 100th anniversary in 2010. A year-long celebration, from January through December 2010, included a school-wide trivia contest, special pages on the website to commemorate the 100th anniversary, a special 100th assembly, a "birthday party" in December, and the production of a beautiful coffee table book detailing the history of Tenacre.
Tenacre’s At The Forefront campaign, which raised $9 million, helped update and expand the campus facilities. In October 2016, Tenacre started construction for multiple new and improved spaces on campus. Construction was completed in August 2017, in time for students to use the new facilities when school started in September. New facilities from this campaign included the Christian B. Elliot Community Center, Linda B. Nitschelm Dining Room, Casey Hatheway Dunne '11 Stage, a state-of-the-art science center with dedicated classrooms for lower and upper grades, expanded kindergarten space, and additional teaching space. The Schoolhouse was also connected to the main school building.
Will Crissman became Head of School in July 2018, when Chris Elliot retired after 23 years.
Today, Tenacre enrolls 195 students and has 56 staff members.
