I encountered Dan in Philadelphia as I made my way as an adult in my first professional job circa 1981 - 83. I made my way to Philly at least a couple of times from Central Pennsylvania (4 hours), to do one program or another. I'm recalling a teacher training weekend I went in for. I remember not all of us having time to actually present what we prepared in one part of the weekend...and his using the marker of having looked at our practice books, and deciding who would go first, based on how much they had practiced over a period of time. Just noticed yesterday Dan's being close to passing, and now having passed. This is a big loss for us. Warmest regards especially to his family & friends. Glad to hear he's been in Halifax. All best, Ira Zukerman, DC
