Why choose us?

In my previous career as special agent for the Air Force Office of Special Investigations (AFOSI), I was skilled at conducting a broad range of tasks ranging from homicide investigations and personal threat assessments to counterespionage.  After retirement from the Air Force I served as the Director of Forensic Science for the Austin Police Department. In later years I carried my passion for forensic science and teaching to St. Edwards University where I was responsible for developing their forensic science undergraduate degree program.

I also contributed seven years as aboard member (last two as President) for The Texas Association of Licensed Investigators (TALI), one of the largest and top P.I. associations in the nation. I am one of under 40 in the state that has achieved the distinction of being a “Texas Certified Investigator (TCI)”. I am also licensed in Alabama and Louisiana.

I mention all of this to emphasize that I have the tools, background, experience and training needed to provide you with the best and the most efficient and effective safety, security, and investigative services.

I have a genuine passion for safety and security awareness and education — helping individuals and institutions become less vulnerable and more aware of potential risks and threats so they can improve the safety and security of their surroundings.
