Remembering Don

I have the fondest memory of Don. He has been a great colleague a great asset to Sloan and MIT in general. He always went above and beyond what was asked of him. I remember particularly well when I taught an LGO course for the first time and how Don was supporting me in every possible way. I also loved running into him at ski slopes. He was an avid skier. I always admired his physical fitness and I could only wish to have that level of fitness and skiing ability at his age! We will miss him greatly!
