I had the privilege to have interned under, been trained by, and to have been an associate of Morris Covin and Associates. In the four years prior to Morris’s death in 2008, I administered polygraph examinations of all types for his clients.

Morris Covin was a preeminent polygraph examiner for over forty (40) years. It was an honor to have assured him that his client’s polygraph needs would continue to be met professionally. As a continued reminder of that commitment and in remembrance of my friend, I use his logo as my own.

In Gratitude,

Earl G. Sturrock
