Mark Siesel made taking care of my traffic case easy, and delivered with results. Mark was professional, prompt with return calls or emails, and very efficient. He followed up on the day of my case, and took care of everything as promised. I would recommend Mark highly to my friends or colleagues in the future should they require his services.


Recently, I had a legal situation that required the assistance from an attorney. Well, not living in the State of New York I had to do some research regarding qualified attorneys in New York. I found Mark Siesel. I'm happy to write that Mr. Siesel came through with "flying colors." Mark made sure my rights were respected as guaranteed by our constitution. There is but one thing that I want Mark and his office to know: I'm totally grateful to have found him. Thank you very much Mr. Siesel for your professional assistance in this matter.


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.

Hello Mark, I so appreciated for your service. I would definitely recommend you to other truck drivers for their traffic violations.


Mark was an extremely effective and professional attorney in handling my DWI case. From the moment I contacted him, he made me feel at ease and hopeful in reaching a positive result. Mark listened to and addressed all of my concerns, including issues with living out-of-state and potential employment ramifications if I received a DWI conviction. He worked diligently and closely with me each step of the way during the duration of my case. Mark succeeded at trial in reaching the best possible outcome with the least impact on my life. I am extremely pleased with Mark's services and forever grateful for his hard work. I highly recommend Mark to anyone with a traffic offense or arrest in Westchester County.


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.


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

Dear Mark, This note is to thank you for the excellent way that you handled my various traffic offences and multiple tickets that I had received from the police in White Plains. I was impressed with your advice, independent research and findings that ultimately determined a favorable outcome in court for most of the tickets, especially the one that was wrongly issued to state that I had no Driver's license at the time of the incident. I want to assure you that I shall inform friends, family and colleagues of your friendly, open manners, and high level of professionalism." Best wishes always.


Mark is an experienced and smart DWI lawyer that understands the system well, especially in Westchester. Mark helped me get through my DWI infraction and provided sound advice all along the way. Mark's strong rapport with the judge and recommendations for particular evaluators/counselors minimized the conditions of my sentence. I thoroughly recommend using Mark for any DWI or driving related cases.
