Mr. Petrillo: Savior at Law
In early 2012, I was wrongfully accused of arson via circumstantial evidence. The lead detective was determined to have me suffer for someone else's crime and I felt powerless. Mr. Petrillo saved me from my Kafkaesque nightmare through his strength of character, confidence of law and learned talent i...
"It's no coincidence that most times someone involved with law enforcement gets in a jam (ie. cop gets arrested), they retain the services of Bill. His case outcomes speak for themselves. He is an excellent litigator, well-respected advocate & gentlemen."
"I highly recommend Mr. Petrillo for anyone looking for a top notch criminal defense attorney. Mr. Petrillo is kind, intelligent and a skilled advocate. He goes above and beyond for his clients to ensure the best possible outcome for their case."
"I endorse this lawyer. Bill is simply one of the best trial lawyers I have ever had the pleasure of knowing. Dedicated, thorough, an expert at cross-examination and a sharp legal mind. On top of that, he is personable and cares deeply about his clients. I wholeheartedly endorse him for anyone seeking a criminal defense lawyer."
"Having known Bill Petrillo for many years, I can state without reservation that he is in the top 1% of trial lawyers. Bill started out working in law enforcement and then for the Nassau County District Attorney's Office where he was one of the most active and successful trial lawyers in the office. That background -- coupled with Bill's raw intelligence and solid work ethic -- gives Bill an arsenal of weapons in the courtroom with which he gains acquittal after acquittal of cases that appear impossible to win. Bill is the lawyer whom judges, other lawyers and prosecutors go to when they need representation. And Bill's ethical and professional standards are impeccable. Bill not only is an asset to the bar; he's an asset to the world. He is an outstanding lawyer and an outstanding person. Anyone who is fortunate enough to have Bill as his or her counsel could not have better representation."
"I unconditionally and heartily endorse William S. Petrillo, Esq. I am the owner of one the largest Personal Injury and Civil Rights firms in New York. I am on the Board of Directors of the New York State Trial Lawyers Association. Over the years I have referred Mr. Petrillo numerous clients who required a criminal defense attoney. I have also collaborated with Mr. Petrillo on a high profile nationally known civil matter involving a the wrongful conviction of an innocent man who spent 18 years in prison for a crime he did not commit. Accordingly, I am uniquely qualified to attest to his professional abilities. As a criminal defense attorney, he has a well earned reputation of being both well respected and feared by his prosecutorial adversaries. He has a “no holds barred” tenacity in the defense of his clients. He has successfully defended some of the most difficult high profile and media cases. Mr. Petrillo is a tenacious, aggressive and unyielding advocate for his clients"
