Denis has enthused and inspired many educators at their schools and district headquarters and as the keynote speaker for Social Studies Conferences (NYCSS). He has held workshops for teachers at state conferences, including the NY State PTA as well as PBS’ Celebration of Teaching and Learning with WNETs (Channel Thirteen) multiple years in a row.

He continues to work closely with leading educators from independent and public schools across the country, fine-tuning his live talks, ‘Explorer-in-Residence’ workshops and now ed-tech best practices to fit their various needs. He offers varying levels of PD, dependent on the elements of the chosen program. These may include phone calls, Zoom sessions or in-person visits leading up to his visit and on-site professional development sessions with select members of our team.
