Jacqueline Yang, Ph.D.


In November 2018, I had the opportunity to attend the “Personnel Security Clearance Adjudication Process for Government Contractor Employees” class held by Mr. Daniel Herdman. Over the past several months the content he provided has proven to be timely, on-point, and current. I wanted to take a moment and commend Mr. Herdman for not only providing solid information, but for his professionalism and kindness in handling follow-up questions in a prompt and concise manner. I have and will continue to recommend his class and services now and in the future.
