Lisa D. was the Head of School at Wilmington Friends when I first enrolled there. And similar to Landis G., she took a chance on me, really setting in motion the series of good events that has been my life since.
What I remember about Lisa was that she was soft-spoken, and kind, but could be tough when she needed to be. She was the kind of teacher (and leader) that you didn't want to disappoint. Neither she nor Landis are at Friends anymore, and I'm not sure the School could possibly feel the same without them.
