About Us

David C. Pelachick
Licensed Pennsylvania Private Investigator
Certified Polygraph Examiner

      I have been conducting Criminal Investigations and Polygraph Examinations for 30 years, most of which were during my career with the Pennsylvania State Police.

     I earned  a Master's Degree in Law and Legal Studies and am currently a full member of the American Polygraph Association and the Pennsylvania Association of Licensed Investigators.
