He may be gone, but look at where we are because of the likes of him! We can reach the heights we do because of those that went before us. Those that took the wisdom handed down to them and built on it again. We really do stand on the shoulders of giants.
Some might say we'll never see the likes of him again. Well, that may be. But those following us won't see the likes of us again, either. So in the memory of Dean, in his honor, and to your own honor...find a student and teach them what you know.
