When we came to his office we were devastated, full of fear, with a long sentence offer of over nine years. Science that day forward a continuous fight continued, with had no hope and we had no faith in anyone. But since day one and throughout the case he continued telling us to have faith in him, that one day we would give him a big hug saving my husband.

The road was not easy, and i lost my faith many times. He worked  with him almost every other week meeting and getting documents he would ask for.The result came out to be amazing and even after this huge victory he continued helping us in other things not fully related to his case. He also has a great team which they always have a way to find an answer to every little issue.

  • Marc Seitles and his law practice come highly recommended by myself and my family. Through what can be some rather harrowing times and downright scary moments, Marc and his staff were kind, professional, and tenacious in the delivery of the justice that we sought. Unfortunately it's in times of great duress that people turn to others that make them all sorts of promises. I hired Mr. Seitles and I can very boldly claim that Marc was always realistic and optimistic through every step of the journey and deserve to be a best Criminal Defense Lawyer in Miami. I am proud to call him my friend at this point and urge anybody looking for this type of legal service to give him and his offices a call.

  • The only Criminal Defense attorney in Miami you can trust, and believe me I tried some, when you are in trouble the lawyer can become your worst enemy, not the case here, a decent ethical man that will treat you as family and fight for you till the end. When he shows up and tells you this is war! He means it! And you know what it is really war, and he doesn't know how to lose.

  • My attorney Marc Seitles helped me with my long ridiculous sentence and I was destined to die in jail without ever harming anyone. I am so happy with Marc's representation. I firmly believe that God put him on my path. He used Marc's great intelligence and deep insight of the law to free me from a sad faith. I remember the first time I spoke with Marc he promised me that he would fight for me like a beast and he did! Marc along with his marvelous legal team which are great loving people, compassionate individuals that do not treat people as mere case numbers but as actual people in distress with a great need of relief. I am overall super happy for Marc's representation and all his kindness and efforts with my case.

  • For the attorney Marc Seitles I only have to say thank you thank you thank you. His job has been so honest and sincere which has allowed me to enjoy my freedom and be reunited with my son and my family here in Colombia. He is an amazing person that works very hard for all his clients and can be trusted 100%. Mr. Seitles tells you how it is and his fees are affordable. From the bottom of my heart Marc I want to say thank you and I know that God placed you in my path and I thank him for allowing us to meet. I was arrested in Colombia and pregnant and extradited later to the United States and had to leave my newborn baby behind but you came from heaven to help me with my case and you have for sure a gold medal in heaven. I wish you the best in your professional life as well as in your personal life because you deserve it.
