Very Professional
Walt Disney once said that, “Do what you do so well that they will want to see it again and bring their friends.” Mr. Hannan was whom he was speaking of. So here is my request to friends. We had a situation where we felt we were taken advantage of. Mr. Hannan not only explained in honest and clear way of how the case would proceed, he was exactly right. There was absolutely no surprises, which is all I want from an attorney. While I understand you can't win every case (which we did get the settlement he said we would), you can expect ethics and Mr. Hannan is the epitome of that. Going forward, while I hope I never "need" an attorney again, I will "want" to see him in action as he is fantastic.

Patient and Informative
Mark represented us in a lawsuit that was stalled by the opposing attorney at every opportunity possible. Mark did everything correctly to continue the case moving forward in our favor. Additionally, he explained all the options we had at every step in the process and proceeded based on our decision. I hope that we don't need him again, but if we do, he'll be our first call!

Prompt, Professional, Courteous!
Mark helped me avoid points and a heavy fine on a speeding violation. He always answered or returned my phone calls right away. It's hard to find a lawyer who truly cares about his clients. I'm lucky enough to have found one and I won't use anyone else. Highly recommended!

Super grateful for Marks help with a very serious incident.
I had a nightmare of a situation involving an arrest in New York City. and potential charges that could have ruined my record for life. I was extremely worried about the money and consequences because I've had lesser issues in the past that were expensive to fight in court. Not only did Mark get all the charges dropped, what could have easily costed me over $1,000 in court fines, I literally only paid the cost of the court fee which was $36. Mark was well spoken knew how to handle this judge in particular and had us out of there in 30 minutes. Mark was a great help, glad I found him.

After getting caught up with the law for the first time in my life, Mark Hannan helped me navigate this complicated environment with intelligence, confidence and ease. Faced with an uncertain upcoming verdict, Mark was able to get my sentence reduced to the BEST possible outcome. I owe him a debt of gratitude and I have total confidence recommending him to handle any of the many legal issues that someone may run into during a lifetime.

Mr. James V. Nocito
Mr. Mark D. Hannan represented our Organization, and, by association of the subject matter, other similar Organizations, with an Opinion pertaining to proposed changes to local zoning laws. The changes would make it difficult, if not fully impossible, for Organizations such as ours to function or even exist. Mr. Hannan, operating in an accelerated time period, was able to: gather together all applicable local zoning laws; understand how said changes would adversely affect Organizations such as ourselves; and put together a well executed Opinion that clearly stated the Legal reasons for our opposition to the proposed changes. I've personally worked with competent Lawyers multiple times in the past, and, in my personal opinion, Mr. Hannan's professionalism, efficiency and knowledge of the subject matter put him at the top of that very esteemed group.

Great Results!
Mr. Hannan was very professional, knowledgeable and helpful from day 1 of the process, his efforts in my case went above and beyond. I appreciate all the help I received from Mr. Hannan.

Trustworthy and Reliable, with Results
Mark Hannan's legal services were exactly what I needed in my situation. I had received criminal charges that I believed to be unjust and consulted with Mr. Hannan. He explained how the whole process would work to me, got my court date postponed to a date convenient for me, and put me at ease heading to the appearance. He came prepared with specific legal references to support my claim. He met with the District Attorney before my time to appear and calmly and professionally stated our case while building a good working relationship with the DA. The DA saw our side of the story and dismissed the criminal charges without the need for a trial. I payed a small fine as my part of the deal and most importantly, have no criminal record. I do not believe I would be in the same situation without Mr. Hannan's services and I am glad I called him.
