Bill Fitch, formerly WT’s Assistant Director of Athletics, has become the Director of Athletics.

With this deep WT background, Fitch is well-positioned to foster an atmosphere conducive to developing WT’s student athletes within the framework of the school’s Mission.

Fitch received both a B.S. in Elementary Education and an M.A. in Educational Administration from Point Park University, and has been a regular WT representative at the National Association of Independent Schools’ People of Color Conference. In addition, he has supported the school’s work with FAME (Fund for the Advancement of Minorities through Education) and Kids of Steel.

Dana Kooistra joins WT as Director of Upper School. A veteran independent school educator and administrator, Kooistra most recently served as Associate Dean of Academics for Teaching, Learning, and External Partnerships at The Lawrenceville School where she also taught grade nine history and upper level interdisciplinary electives (Bioethics, Immigration, and Race & Mass Incarceration).

Kooistra was a founding faculty member and admissions director at CITYterm, an experiential semester program focused on New York City, and she was an instructor with the University of Pennsylvania’s innovative Independent School Residency Program.

A graduate of Wellesley College, Kooistra also holds an M.A. in Educational Philosophy from Teachers College, Columbia University, and has attended Columbia’s Klingenstein Summer Institute.
