The team at Cornerstone Research has accumulated over fifty years combined experience in developing, selling and supporting radio software. Several team members have radio programming experience, giving us essential insight into our clients’ needs and how they do their jobs. 

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!

Dale Radtke - Senior Software Architect
Dale Radtke enjoyed five successful years at Tapscan/Arbitron working primarily on TapMedia, the web-based delivery and production system for customer downloads. Prior to joining Cornerstone Research Dale had an extensive background developing web-based and desktop software applications and worked for Microsoft in the Seattle area before relocating to Alabama.  Prior to that he served in the U.S. Army for 20 years, as a pilot and intelligence officer.

Geno Pearson - Music Product Specialist, Hook Exchange
Geno’s career started in Houston as Music Director for KHMX where he worked under PD Guy Zapoleon. Geno has also programmed stations in Oklahoma City, Greensboro and Birmingham. He also participated in the Active Industry Research (AIR) competition for Fall 2001 and placed 2nd out of 100 PD’s and MD’s from across the country at predicting the chart success of new records that come out each week. An expert in (and fan of) music of all genres, you don’t want to play Geno in music trivia!

Angie Owens - Product/Data Specialist, XTrends and The Analyst
Angie joined Cornerstone as another Tapscan/Arbitron alumni. During her tenure there Angie worked extensively with many forms of quantitative and qualitative data as well as managing development of data processing systems. Angie is in charge of all our data processing, both music and ratings research, plus she’s vitally involved in product management and support. We keep Angie busy!
