About Us


Historically, access to forensic services has been limited to government sponsored laboratories and specialists, leaving access to these services out of the reach of all but law enforcement agencies. Not until recent years have these services been made available to legal defense teams and the private citizen attempting to ensure that just and equitable trial procedures are fairly met.

As crime scene analysts and other forensic specialists became available, defense counsel and citizens privately pursuing legal actions quickly recognized the benefits of having physical evidence reviewed and processed by an independent and qualified expert. It was not long before the demand for skilled forensic specialists outpaced the availability.

In 1996, Lisa Allyn DiMeo founded Arcana Forensic Services to provide for this communal need. Since that time, Arcana Forensics has provided professional, skilled and qualified forensic support to cases throughout San Diego County and the United States.
