“I am a high school principal and my school is located in Memphis, Tennessee. I had a mysterious document to appear in a class that troubled me. I looked throughout the city in search of someone who could help identify the author of the document. I found no one. I then moved my search from the yellow pages to the internet. It was there that I found Dianne Peterson. Once I explained the situation, she gracious took on this case. Because this was not a legal matter, I did not know what to expect. We are a small charter school who values the scholar’s safety. Dianne was patient and very thorough.

“For eight years I had been fighting with the United States Department of Education over the fact that someone had forged my signature on some loan applications and I was being charged $75,000 for student loans which I never received. I tried explaining to the Department of Edu. that the applications and signature were not mine. The Department of Education after several times reviewing copies of my real signature and writings from that time period of 2001 ruled that the writing was mine. They told me my only chance of proving otherwise was to find a professional handwriting expert to verify my claims. I went to my local sheriffs department and prosecuting attorneys office but no one would assist me in finding an expert to help me. Finally my girl friend found you on the Internet and we spoke and I explained to you my situation.

From my initial conversation with you I immediately knew I was dealing with a person who is both professional and extremely knowledgeable. You were straight forward, clear and concise as to what I needed to do to allow you to verify assertions. I forwarded to you the documents you required to ascertain my claims and in a short time had contacted me back that you had received the documents and that in your professional opinion would verify my claim that those documents in question were not written by me.

When you told me the cost of your service, which I was expecting to be over a thousand dollars and it was much less than I had expected, I was extremely pleasantly surprised.

Then to top that off, you went over and above my expectations and in stead of just sending a certified letter to the US Dept. of Edu. rendering your decision you filed an affidavit. With your help after me dealing with eight years of stressful aggravation with the Dept of Edu. you saved me $75000 and ended my nightmare. I am so Thankful to you and wish to tell you, you are awesome and a hero to me. Thank You Thank You Thank You” – Lane Baumgardner, CEO Meteorite Exchange Inc.

I am happy to write a review regarding my experience with Dianne Peterson.  I was recently the victim of a person who forged my name on a Promissory Note that she recreated to replace the original Promissory Note in an attempt to defraud me out of $4000. Because of Dianne Peterson’s prompt and thorough review of all documents and a beautifully prepared report by her, I not only won my case regarding the $4000 but the individual was charged and pled guilty to Forgery. Ms. Peterson explained her clear and concise findings in a manner that the judge had no problem reviewing.  If I had not sought out Ms. Peterson I find it highly unlikely that justice would have prevailed. Many thanks to Dianne and her staff for their help in this matter.  Should I ever find myself in need of a handwriting expert again, there is no doubt who I will call. – Julia D’Hondt Alabama
