Here is a small sampling of what clients had to say about the representation they received by The Law Office of Mark A. Siesel.

I am very thankful to Mark. He was very informative in answering all my questions, very accommodating and eased my worries. The best attorney, he helped me with my case (car accident) when I was completely lost; he is really comprehensive and professional.


I was in a horrific train accident. After my first phone conversation with Mark, I knew that I made the right decision. He was compassionate, knowledgeable, and extremely accommodating. He was with me every step of the way and he was very informative. His advice and counsel comes from many years of experience. My emails were always answered, my text messages were consistently responded to, and my phone calls were all returned promptly. He personally negotiated my very fair settlement and I finally had some closure with my unfortunate ordeal. My family and I are grateful to Mark for handling my case with his usual thoroughness and passion for his client’s best possible outcome. I would never hesitate to contact him in the future if the need arises or recommend his services to others. Words can never fully express my gratitude but hopefully these words come close.

Mark is an amazing attorney! My family has been using his legal services for years. He's compassionate, experienced & dedicated. His staff, (specifically Nina) was great at keeping me in the loop. I was in a car accident not even a year ago & already received a settlement. I'm so grateful for all he's done & would highly recommend him to anyone!!


Great representation and very passionate and dedicated staff. I would highly reccommend this law firm to anyone in need of competent and knowledgable attorney work throughout Westchester County. Mr Siesel is a true professional and his staff is amazing and very helpful. Dont hesitate to call!!

I was involved in a 4 car auto accident while driving home during rush hour in summer 2011, not knowing my rights and what were my options. I went online to search for a lawyer that could help me along with my case. After contacting a few lawyers I felt that Mark Siesel had the most experience in my kind of case. After meeting with Mark Siesel I felt that I was in good hands. I was kept up to date with my case and he always explained what my options were. I'm very pleased with my decision to go with Mark Siesel. I would recommend him to anyone needing his services.


Mark is a phenomenal attorney. He rigorously dedicated himself to obtain a favorable outcome in our case. Aside from Mark's proficiency as an experienced lawyer, he is also very personable and always extended himself in order to answer any questions or address any of our concerns about our lawsuit. I believe it is rare to find a lawyer who is genuinely a straight shooter and Mark exemplifies this attribute.


At the time of the car accident in which I was rear ended and suffered injuries I had no clue what to do or how to proceed after the shock and trauma caused to me and my daughter who was a passenger. Fortunate for me I had a close friend who recommended you and your practice. I wish to express my appreciation for services you provided to us at a time of great need. Your hard work in my case made a big difference. Once again I wish to THANK-YOU for the work you did on my behalf. Muchas Gracias Por todo el trabajo que usted hico por mi en el caso de mi accidente. Estoy muy agradecida!

Betty L./ a very grateful client!

While we were visiting White Plains, my wife had an accident that left her with permanent injuries. Being from out of state we certainly did not know exactly what to do or who to turn to for help. After contacting and talking with Mark Siesel, I was sure we made the right decision to have Mark handle our case. Mark was always there for us. He was always available when we had questions or concerns. He kept us up to date every step of the way. Mark was more like a friend helping us get through all of the red tape. Mark's expertise and knowledge brought a somewhat difficult case to a successful settlement. We were more than pleased with the settlement. Mark you are the best. Thanks again, Regards.

PB and SB

When Mark expeditiously and successfully settled my case, I said "it was a pleasure doing business with you". Now, how often do you say that these days? Mark's knowledge and experience guided me throughout the process and as a result, I was able to completely rely on him without fear or worry. I would highly recommend him as an attorney and would not hesitate to call upon him in the future.


Mark Siesel has represented my family three times over the last fifteen years. Two were personal injury cases and both were settled much higher than we expected. The other was the first time my son got himself into a little trouble and thanks to Mark Siesel my son has a clean record. I cannot emphasize enough what a difference having an attorney like Mark Siesel on your side can make. From the first time you meet Mark you will feel comfortable and know you have a personable attorney on your side. After you choose Mark Siesel you will never need to search the internet or a phone book again. With Mark you will have a family attorney to handle all your needs and more important a friend you can trust. My family and I can never thank you enough for what you have done for us.


My initial phone call to Mark Siesel left me with such a favorable impression that I ended my search for an attorney without ever calling the others I had researched online. Since then, as Mark skillfully brought my personal injury lawsuit to a speedy and successful conclusion, he not only lived up to my expectations, he surpassed them. Always accessible and attentive, Mark responded to every e-mail and phone call ASAP. In the end, despite various odds against my case, Mark achieved a settlement that was more than I had hoped for- all in less than a year, without the inconvenience of a trial or any hassles at all.

E.B., former and future client

After my accident, Mark was one of several lawyers I spoke with. I had no experience in this area and was concerned with obtaining legal insight that would provide direction and safeguard my welfare. The difference in quality and respect was immediately noticeable upon speaking to Mark. Mark has proven to be superb. I undoubtedly will recommend him to anyone seeking legal counsel!! THANK YOU!!! Kindest Regards,"


" Mark was extremely helpful and caring during my case. His experience and knowledge of the court system was a tremendous help in getting the best possible outcome. Mark's advice was practical and well thought out. He was responsive and worked hard on my behalf. I would highly recommend his services to anyone who wants to have the best possible representation in a Westchester courtroom.

S.M., former client

Mark Siesel you are the best!!!!! When we came to you after my husband's accident you were always there for us. You made us feel comfortable from day one. You never let us down and we THANK YOU !!!!! for that. You were always professional and kept us well informed. I would recommend Mark Siesel to anyone needing a lawyer after an accident. We were very lucky to have you represent us. Thank you.


When your 19 year old son is in a terrible car accident, one is not thinking of lawyers. We feel very lucky to have Mark be the one that represented us. In a low key way, he guided us through confusing hospital red tape, answered questions and was quickly and consistently available for all our concerns. He treated the entire family respectfully and our child as an adult. He was there for us through a most difficult time with the right amount of information that minimized our being overwhelmed. He obtained a settlement for our son that means so much to him in moving forward from his ordeal and subsequent impact on his life. He did not have to go to trial. Most of all, Mark was decent, honest and trustworthy and we will always be grateful for what he negotiated that will be of great service to our son in his lifetime.


I have worked with trial counsel for both plaintiffs and defendants in various types of personal injury actions throughout my 18 years of practice. Based upon my experience, I can unquestionably endorse and recommend Mark's services. He develops a strategy for his case early on and thoroughly prepares for trial. He is candid, forthright, and respected by members of the bench and bar, for good reason.


I write to thank you for recommending Mark Siesel to me when I was seeking an attorney to handle my wife’s auto negligence case. Mark did an excellent job and was attentive to us throughout the course of the litigation. The case settled recently due to Mark’s unstinted time, efforts and skill, and we are grateful to Mark and to you for recommending him.

Whatever praises I say for Mark would not be enough... Having had a severe no fault accident as a limo driver with injury to myself and substantial medical bills to pay, I received a claim from one of the clients who was in the car. Long web search led me to Mark. His name stood out. Despite the fact I currently live many hours away from NYC, he managed the case as if he was next door. All calls and emails were answered promptly. I was diligently updated on the case. He has done an excellent job dealing with insurance company to settle the case in a timely fashion. He is very approachable, dependable, and knowledgeable. I am so grateful to Mark and would highly recommend him to anyone who needs professional help and humane attitude. It is so great to know in time of stress and worry someone is there for you. THANK YOU, Mark!!!


Mark Siesel represented me in a personal injury case. I was extremely impressed with his work for several reasons. He was very professional, committed and thorough in the entire process. Mark's persistence and compassion reassured me that I was never alone. He completed his work promptly and returned my phone calls the same day. He was very supportive and extremely patient, explaining everything in detail to me. His experience and knowledge were very evident throughout the proceedings. Mark's professionalism and integrity were exemplary from the beginning to the end. I implicitly trust him. It was a pleasure collaborating with him. Through mediation or litigation, Mark is resourceful in getting you the best results.

L.A., former client

Last year, I was in a very bad car accident with a New York City construction truck. I immediately retained Mark Siesel to represent me, as he had previously represented members of my family in other cases with excellent results. Mark handled all aspects of my case thoroughly and aggressively, from fighting with the insurance companies regarding my medical expenses to litigating the case against the City of New York. My phone calls were always returned the same day, and always from Mark directly, not from a secretary who might not have been familiar with my case. Within a year, without having to go to Court, I got a substantial settlement from the City for my injuries. I would highly recommend Mark Siesel to anyone who needs the services of a thorough professional who gets the job done quickly and effectively.

J.D., former client

There is no one better than Mark Siesel. He is honest, fair, caring and gets the job done. I felt confident knowing that Mark was representing me. He is a true professional. I would recommend him very highly.

P.A., former client

Previously my opinion of lawyers was rather jaded and not very respectful. My prior dealings with lawyers before retaining Mark Siesel left me feeling frustrated and defensive. When I had a motor vehicle accident and needed a lawyer, I went to Mark. From the initial visit I had with him, through the end of the case, I felt comfortable, confident, fully informed, and trusting because of the way he treated me. He always returned my calls the same day, and was always available to explain what was happening in the case in language I could understand. I highly recommend Mark not only for the above reasons but for his bright intellect and ability to look at a situation with unusual observations. My case was approached from an angle that surprised and delighted me and we won!

E.S., former client

B.B., former client

In 2003, I was involved in a terrible automobile accident and suffered severe back and neck injuries. I did not know of an attorney and requested that a friend of mine, whose son had been in a serious accident and was represented by Mr. Siesel, give me his number. Mr. Siesel was able to visit me that same day, and from the minute I met him, was caring, concerned, and immediately began working on my case with professionalism and purpose. Mr. Siesel won my case for me, and is a dedicated attorney who will certainly give 100% for his clients. Additonally, his staff is competent, professional and dedicated, and always a pleasure to deal with.

L.C., former client

" After enduring the trauma of a severe car accident, I hired Mark Siesel to represent me. As a result of Mark's professionalism, vigorous efforts and substantial knowledge backed up by almost twenty years of experience, he obtained a prompt and successful settlement of my case. Additionally, Mark was extremely helpful in dealing with my insurance company to assure that I received medical care in a timely fashion.

R.K., former client

I'm writing this note on behalf of my lawyer, Mark Siesel. He was recommended to me by a friend who works at a well known law firm in our area. Mark immediately called me and came to my home to meet me as I had severely fractured my ankle and was unable to get to his office. If ever I had a question, Mark and his wonderful staff were always very helpful, courteous and professional. Mark succeeded in winning a large settlement in my case. I would strongly recommend Mark Siesel to anyone as he demonstrated his expertise and abilities in handling my case expeditiously and professionally.

S.B., former client

Our son was in a very serious head on collision, suffering from brain trauma and pelvic fractures. He was in a coma for one week and in the hospital for a month. When we decided to speak with a lawyer, we were ambivalent as we couldn't handle the stress of even gathering papers together. Having had unpleasant dealings with lawyers in the past, we were concerned about unanswered phone calls and lack of attention to the case. Mark came to our home and we were surprised and comforted by his caring and honest character. He handled all of the paperwork and every phone call was returned by the end of the day. Never did we think there was a lawyer who was capable of doing that! Mark handled all the legal stress so that we could concentrate on our son. My son received a very large settlement quickly and without going to Court. We truly believe that we would not have gotten the same attention and compassion if our lawyer had been a member of our own family! We have since retained Mark in several other matters and have always received the same warmth and sincerity that we did on the first visit. We will continue to recommend Mark to friends, family and acquaintances and utilize his services whenever the need arises.

T.W. and D.W., former clients

I was so lucky Mark was recommended to me by an acquaintance. He handled my personal injury claim and protected me from the ordeal I would have faced on my own. He is honest and trustworthy. He watched out for my interests every step of the way and did a terrific job representing me. It pleases me to have this opportunity to praise Mark Siesel in this forum.
