Posted by CHRISTOPHER | February 12, 2022 | Hired Attorney | Sex Crime

The best decision I made was hiring Sean Mangan!!!!!

False Sexual Assault Charges were brought up to me in April 2021 (Article 120 and Article 93). I am part of the Special Operations community at Ft. Campbell. Sean always kept me informed through the process and was always very patient with any questions me or my family had. There was another inci...dent that arose during this process and he helped me with that situation as well with no hesitation. His expertise during the court martial led to the best possible outcome for my case. Him and my trial defense counsel got me acquitted of both charges that were brought against me. My 1SG was making unnecessary comments after the whole ordeal was over and Sean called our legal team and told them they needed to put a stop to it. Even after our contractual representation was done he was still helping me out. This says a lot about his character and what an amazing individual he is. He genuinely cares for his clients!! I am forever in his debt for his relentless persuit of actual justice and his unparalleled knowledge. If you ever find yourself needing legal representation I STRONGLY RECOMMEND YOU HIRE SEAN MANGAN!!!! He is the best option for a favorable outcome in this military “Justice” system.

Career Saver

Mr. Mangan was recommended to me by Senior Leaders who have had to work against him in the past. I was told that if there is anyone who can mitigate any negative UCMJ, he is the one to call. Sure enough, blind-sided and completely lost with how to defend myself, Sean stepped in and guided me throu...gh the entire process all the way to a favorable end-state that I'm certain would not have been possible without his assistance. He undoubtedly saved my career in both the short and long term. In the unfortunate event that I'm ever faced with UCMJ again, Mr. Mangan will be the first person I call.

Outstanding Military Lawyer

If you need a lawyer that knows military law, look no further. Sean was very knowledgeable and after reviewing my allegations was able to get them dropped and I walked away with just counseling from the commander. This is your guy he will not backdown to anyone no matter what. Thank you for saving my... career.

Saved My 30.6 Years of Service

SEPT 2019 I called Sean to assist me with rebutting a GOMOR. I was falsely accused of Misconduct which could have ended in a dishonorable discharge. I used the TDS, who presented the fact in the case, nonetheless the higher command ignore the facts. A friend Google "the best civilian military lawye...r who knows GOMOR. Google found Sean Mangan. Sean was professional from the beginning. He is an experience formal Military SJA. He went to bat for me from the beginning until we became victorious. All of the charges to include GOMOR was unsubstantiated. Sean did not give up the good fight. When our day came to present the case to the Board of Inquiry (BOI), Sean became IRONMAN and fought back. Sean Mangan is my and I superhero for life. Sean saved my retirement, my career, and my integrity. I recommend Sean Mangan to any Soldier, Sailor, Airman, and Marine. Sean, thank you so much for your time and attention to my case.
