The managing director of Pelham Associates is Prof. David M. Frankel.
While a PhD student at MIT in the early 1990s, Prof. Frankel worked at the Brattle Group. From 1993-4 he worked full-time as a research associate at Charles River Associates. He learned at these firms how to protect clients via protocols for error detection and correction, document retention, and within-team communication.
From 2004 to 2017, Prof. Frankel ran his own boutique consulting firm, Cambridge Economics Group, where he testified in numerous cases and refined these techniques.
