Excellent experience

Mr. Mangan was assigned to me as my in-person counsel during my Board of Investigation. He worked with my hired attorney for the weeks leading up to the BOI to get caught up to speed with my case and understand the nuances of what had been an almost year-long investigation. He also worked well with... my military assigned counsel, and together they split duties of interviewing fact and character witnesses and preparing my file for the Board. He came well prepared to the BOI and worked with me on making a plan for how to best present the facts of the case. He effectively interviewed my witnesses and helped guide my personal testimony. I found him to be compelling, articulate, and highly effective. I had gone into the BOI confident that the facts of the case were in my favor, but of course nervous that my military career hung in the balance. It was clear he took his responsibilities to me as my counsel seriously and made sure my story was heard by the Board members. I felt well taken care of my Mr. Mangan and by the end of the day thought we had presented our case as well as I could have hoped. Thank you to his assistance, not only was I retained by the military but the Board unanimously found that the accusations against me were not credible. Due to this, I can now continue on my with my career. Thank you, Mr. Mangan.

Article 120, 134, and 92

I was a US Navy LTJG (O-2) up against criminal charges punishable by UCMJ Article 120, 134, and 92: Sexual harassment/assault, distribution of alcohol to a minor, and conduct unbecoming of an officer. This could amount to up to 25 years in prison. I could not believe it. I thought my career was ov...er. I thought I would never find another job again. I thought my life my life was over. If you are wondering when to get a lawyer, the answer is immediately upon hearing there is an investigation going on, EVEN if you are still going to work and showing up to quarters at your command. When I heard about my allegations, I contacted Sean Mangan. Upon hearing my story of what happened, Sean looked me in the eye and calmly said, “I’m confident I can provide the services you need.” And he delivered. He organized his own investigation on what happened, and the nature of the people involved. He has his own team working on gathering as much information as possible. He collected positive evidence that could help at a court martial or administrative separation board. He went above and beyond and was ready to fight for me BEFORE anything was heard from the investigative team – NCIS. He moves quick to drive the process down a favorable path. As a retired Lieutenant Colonel (O-5) in the Army, not only did he surprise me when he knows all branches of the military (Army, Navy, Coast Guard, etc.), but HE KNOWS PEOPLE ON THE INSIDE from all his years of service that can help MOVE THE CASE TO A MORE FAVORABLE POSITION. For me, I went from a possible general court marshal to my command taking no legal action NOR administrative action against me. This is why it is important to HIRE SEAN EARLY ON, not just to dampen the legal blow to your life, but to also save money so you don’t go to a court martial. Through the next 6 months of silence, there were points I broke down, points where I needed to know what was next, and points where I required immediate assistance. He was there for all of it. He handled my insecurities about the process with calmness, professionalism, and constant assurance that everything was going to be alright. Not every lawyer will pick up the phone at 8:30 PM while he is at a dinner party to answer a quick question. Most lawyers do not even give out their phone numbers, so you have to leave a message with their paralegal. TLDR – If you want to win, hire Sean.

Thorough and expedient

Though my case was relatively minor, it had career changing ramifications I just couldn't afford to suffer. Sean took my case seriously and acted swiftly, bringing it to a very favorable conclusion. His experience from his time as a former JAG lawyer shone, and was glad to have the full backing of a ...retired JAG Lieutenant Colonel. I would gladly utilize his services again.

Professional Representation

Sean provided incredible representation from the onset to end state of my case. His depth of regulatory knowledge and law in this niche arena directly rendered a positive outcome in my case. Sean also provided impeccable tracking and detailed notations of all services provided, for accuracy and ease ...of case management. Lastly, the responsiveness and availability of time that was provided for questions, concerns, check-ins and updates, allowed for constant appraisal of ongoings and status changes, which was greatly appreciated.
