We also offer extensive litigation and investigative support in the form of confidential consultation regarding the Forensic Document Examination discipline as a whole including assistance with evaluating and interpreting the credentials and opinions of other practitioners.

Examinations we conduct regularly are: • handwriting and signature analysis • electronic signature verification • and non-destructive ink and indentation analysis.

Our state of the art laboratory contains: • Video Spectral Equipment to conduct non-destructive infrared and ultraviolet examinations of inks, papers, and other materials • Electrostatic Detection Equipment can visualize and develop indented writings (either visible or latent) appearing on the surface of documents • and Other specialized lighting and laboratory instrumentation, including stereoscopic binocular microscopes, to conduct any type of microscopic analysis that may be necessary.
