Mayfield Senior School | School Leadership

Mayfield's leadership team serves as stewards of our cherished Holy Child legacy

Mayfield's strong leadership team begins with the collaborative relationship between Head of School Kate Morin and Board of Trustees Chair Erika Randall. It extends to the school's deeply committed administrators, who bring a diversity of experience and valuable skills to their jobs. We are blessed at Mayfield that our school leadership team puts the care and welfare of our precious students and our calling to embrace Holy Child values at the center of all decisions.
