With over 55 years of experience specializing in the examination and analysis of signatures, writings, and documents, we are one of the most sophisticated private forensic document laboratories in the United States; including the capabilities to perform all aspects of non-destructive forensic document and handwriting examinations. We are often retained (both nationally and internationally) by law firms, government agencies, insurance companies, banking institutions, fortune 500 corporations and other private entities to handle any issue involving the authenticity of documents, writings and signatures (i.e. wills and other testamentary documents, medical records, insurance policy forms, deeds, mortgages, banking transaction documents, contracts and anonymous/threatening letters) in both civil and criminal matters.
