From October, 1970 until May, 2000, I was employed by the State of Minnesota Bureau of Criminal Apprehension (BCA) Forensic Science Laboratory. I have been assigned to the Blood and Urine Alcohol, Firearm and Toolmark and Questioned Document Sections of the Laboratory.

When I retired, I held the title of Forensic Science Supervisor with the responsibility of supervising the Questioned Document, Latent Print, Firearm and Toolmark and Photography sections of the BCA Laboratory. I was also the State's Lead Document Examiner.

In September, 1980, I co-founded Total Security Concepts, Inc. I am now providing forensic services in the area of Forensic Document Examination in civil and criminal cases.
