Brad Riegel - President
Brad Riegel is one of the industry's leading experts on understanding, interpreting and presenting Nielsen™ data.  From nearly its inception, Brad was the lead developer for the Tapscan product.  As one of Tapscan's original hires and its VP/Product Development for fifteen years, Brad has been crunching Nielsen™ data for a long time.  But Brad's not a "wirehead", he's a regular guy who loves and knows radio.  As a former radio programmer, researcher and air personality, Brad brings a broad perspective to all the projects he oversees for Cornerstone Research.

Mark Schreiber - VP/General Manager
Mark Schreiber also developed his chops at Tapscan, where he mostly spent his eleven years as GM of the MusicScan division (MusicScan was the music scheduling program now known as MusicMaster).  Mark's background is in radio programming.  His last gig was with (then) KOB-AM/FM/Albuquerque, where in the mid-80's he helped the stations achieve a 29.3 combo share (12+).  If you want to endear yourself to him, bring up the Dodgers!
