Patricia Fisher has a long list of experience as well as tons of qualifications within the industry of handwriting analysis. She has been published many times amongst many other qualifications. Ms. Fisher testified in my divorce case 2 times. I have been very pleased with her testimony and results of her analysis. My x claimed he didn't sign multiple documents of which I knew 100% and saw him sign. He is a weasel and always tries to get out everything especially when it comes to money. I knew I had to hire a creditable and very experienced person to review his handwriting and the documents in question by him. She is an expert in her field and I would highly recommend her to support your case. Even my x's attorney was stumpped questioning Ms. Fisher. Ms. Fisher left no doubt regarding her analysis. Thank you for a job well done! George Tarnow I am so glad I took the time to find the best in the country to analyze the documents you claimed you didn't sign.

Be careful with these guys, they can be broughta . They examined a lease that was obviously fraud, hand written, spelling errors and even the address of the old people that were supposed to of signed it was spelled wrong. The first name of the landlord was spelled wrong, the address of the forged owners name was not even capitalized and had wrong spelling, a 10 year old could of seen this was a forgery, yet these people at Fisher were paid enough to verify this lease as "authentic" even though another forensic expert with 30 years experience and an expert witness verified it was a forgery. Do NOT go to these guys unless you need a poor inaccurate verification.
