Am I the Jeffrey Breen you're looking for?
I am if you went to school with me at Derby Academy '84, Milton Academy '87, University of Pennsylvania '91, or University of Virginia '96.
I spend my days wrestling with data and business challenges for clients in the aviation industry at Cambridge Aviation Research. I was previously at Yankee Group from 2006-2010 and have worked at some other interesting places too: Smithsonian Astrophysical Observatory/Harvard-Smithsonian Center for Astrophysics '91-'94, SNL Securities '96-'98, and Forrester Research '98-'04.
I may have worked at or with your startup: eSolstice, Network Subscriptions, Navient Corporation. I have completed many IT consulting projects in the aviation industry starting with a 1990 project at Pan Am's 747 refurbishment facility at JFK. More recently, I worked as a subcontractor for SH&E on projects for the National Business Travel Association, Portland Jetport, Cargo Airline Association, New England Regional Airport Council, flightaware.com, Delta, and others.
But it turns out there are more Jeff Breens around than you can shake a stick at. If I'm not the one you're looking for, visit The Jeff Breen Club on facebook where we all hang out.
Where can you find me?
