Who was your favorite teacher as a kid? For many who attended Crystal Spring Elementary in Roanoke over the last 30 years, it's been Wade Whitehead, an award winning teacher who in his spare time spends a lot of time thinking about what elements make for a good teacher, and what good schools do to support that. Now, as he enters his first year of "retirement" from the classroom, he's dedicating himself to sharing what he's learned with teachers, administrators, and even corporate leaders.
