He has a knack for identifying strategic opportunities and the right tactics that can push the message into the mainstream in order to shine a spotlight or apply pressure. In addition to developing organizational strategy and overseeing day-to-day operations, Derek also spearheads special projects — from coordinating track-1.5 dialogues to producing viral and award-winning creative content.
