I am a New York based Forensic Document Examiner specializing in handwriting and signature analyses. I have over 10 years experience at the New York City Police Department Police Laboratory working on high profile criminal cases, collaborating with the FBI, presenting to the Secret Service and have now taken my training and expertise privately servicing the entire country.
My practice encompasses a variety of document examination needs including but not limited to: handwriting analysis, signature analysis, forgeries, disguised writing, counterfeit documents, obliterations, alterations, indented impressions, government documents, prenuptial agreements, checks, wills, trusts, deeds, contracts/written agreements, currency, etc.
Upon request, I am available for expert testimony. I am very well versed in the intricacies of forensic and legal proceedings, and have a vast amount of courtroom experience where I have always been deemed an expert in my field.
I am a professional with a distinguished background of training and experience, and I understand client needs and expectations. I bring over a decade of seasoned proficiency to each case and don’t shy away from complexity.
