Mercer Island’s Yellow Wood Academy has announced a new head of school and relocation to Bellevue in the fall of 2025.

The academy, which was founded in 1983, is a private school offering tailored educational programs — with a focus on small class sizes, one-on-one instruction and a nurturing environment — for students in grades 4-12.

Incoming head of school Tyrell Hardtke, who is currently one of Yellow Wood’s assistant principals, has been an integral part of the academy, according to a press release.

“Tyrell’s relentless focus on students and meeting their individual needs makes her the ideal candidate to lead Yellow Wood into its next chapter. She brings a unique blend of humor, experience, and serious get-it-done skills,” said board chair Jay Heath.

Hardtke said she’s excited and inspired to bring her expertise into her new role.

“As an administrator and teacher in public and private schools for almost 20 years, I have a unique understanding of how vital our educational program is to the students and families we serve,” she said.

The relocation to Bellevue will provide Yellow Wood Academy with expanded facilities designed to enhance the learning experience, including modern classrooms, collaborative spaces and resources to support the school’s emphasis on personalized education and creative thinking, the release states.
