His expertise is vast and I trust him 100%. He is always the first person I reach out to. I recommend John Iannuzzi and his law firm without hesitation.

Highly recommend!
Mr. Iannuzzi and his staff of the Law office of Iannuzzi and Iannuzzi were stupendous. Mr. Iannuzzi is very attentive and willing to assist in answering any and all of your questions. I also appreciate working with people that care for you on a personal level instead of just handling you as a “case“. My family, associates and I used this office numerous times and I can not thank them enough. Mr. Iannuzzi and his staff are highly recommend.

Simply THE BEST!
There is nothing like a good law firm to help you feel protected and watched over while you navigate the complexity of our legal system. The Law Offices of Iannuzzi and Iannuzzi did just that. John Iannuzzi is a mastermind and truly takes care of his clients like they were family.

Knows What He's Talking About!
John Nicholas Iannuzzi is an excellent attorney. This man knows exactly what he is doing in and out of the courtroom. Mr. Iannuzzi initially came off to me as aggressive and thankfully very rightfully so. He has many years of experience in the industry and it shows - he knew how the case was going to play out and im very fortunate to have had him guide the lawsuit out of the rut that I created.

Awesome lawyer, and friend of the family.
I have retained Mr John Iannuzi twice in my lifetime. All I can say is OUTSTANDING! I would consider John one of those attorney's whom doesn't need any introductions. His stoic presence and demeanor alone will make the prosecution bring their A game. Both professionally and personally, I would recommend John Iannuzi and his beloved Son, Nicholas Iannuzi because they are experts in the field. They know what they are talking about as well as have a vast background as criminal defense attorneys. I've witnessed on two occasions where a city dignitary and a "high profile attorney" have contacted him for advice and a direction for defense on case. Expertise just pours out of this man's lips. The confidence, the resources and his expertise is just admirable. I've read past reviews many have left, let my personal account be the deciding factor to retain John's services. First, no one would hire an attorney when nothing is wrong. That's not realistic. We retain attorneys when our behinds are in trouble, agree? Now on both instances in 2009 and 2015, John Iannuzi ESQ has pull my behind out of the fire unscathed. No jail or prison time, no felonies and no community service. My last time I have retained him I was only subjected to do probation based on the nature of the case. However, having said that. John is the "man with the master plan" who is willing to work with you and sit down with you personally as well as professionally to plan the right path for your defense for your situation. Quality, expertise, fairness, and results. This is what you will receive with John Iannuzi. I pray good health and prosperity to his firm and his family for the years to come. Pretty soon I will retain him again for future help on my probation hearing. If you can't remember anything that I stated early, just remember this phrase: "CANT GO WRONG WITH JOHN."

Great Representation
Iannuzzi and Iannuzzi represented me when I bought my apartment. They were very attentive and helpful - the whole process went quickly and easily.
Posted by anonymous | February 25, 2015
A friend referred me to this guy. He helped my friend but when it came to my case, I was very dissatisfied. He talked a big talk when I first met him. I asked his strategy and he said "50 years of experience is my strategy". Been kicking myself ever since for paying $3500 up front and trusting him b/c of the good result he got for my friend. The public defender that got me out of central said "they'll probably knock this down and let you off w/a lesser charge but you'll still have some sort of DUI record". He told me he would get me off. When I inquired about my case his office made it sound like he was waiting for a call back from the prosecutor and that they were working on some sort of deal. Never heard back. When I called/emailed to follow up, I was told I was micromanaging and basically that the state had bigger fish to fry than my little DUI case. In the end...I just had to wait the 6 mos. and he met me and told me basically right when we were going to the judge that we had to take the lesser charge (and still have a DUI record/increased insurance/etc.) or we could go to trial and "probably end up in the same position" (taking a lesser charge and still having it on my record). I have a business to run and needed to drive asap so I had to just take it and have a record. He couldn't do any better than the public defender. I saw no evidence of him working hard to get a favorable outcome. I basically paid him a pretty hefty sum to show up and tell me the same thing the Public Defender told me 6 mos. prior. Stick w/the Public Defender or get someone else.
