St. Louis Magazine Article, September 1998

"… I have worked with P.D.I./SAC on a number of projects over the past several years. In each instance P.D.I./SAC performed the work professionally, effectively and economically. Our most recent engagement involved a security audit of a large local retail shopping center. P.D.I./SAC promptly evaluated the status of the security at the center, developed a plan for the improvement of the security and implemented the plan successfully. P.D.I./SAC completed the assignment well ahead of schedule and allowed the center to improve security without increasing security budget. Based on my experience with P.D.I./SAC I would recommend P.D.I./SAC for security and investigative assignments."

"I have worked with Michael Barbieri and the staff of PDI over the course of the past two decades as a trial attorney, and I have found their work ethic and integrity to be unparalleled. Every job has been completed to my satisfaction, regardless of the difficulty, and it is often the difference that helps us prevail at trial.

"As I have said to every trial advocacy class I teach, preparation is the key to success, and PDI is an indispensable tool in that process."
