The man you need in your corner.

I'm a E6 SSG AND I was accused of a military SHARP case. The ARMY was dragging my through the dirt. I called around and kinda got the same BS from every law Firm until Sean called me back and walked me through every step, and this was just the consultation. I hired him on the spot. He was with me eve...ry step of the investigation. When we were in the "waiting period" he called every so often to make sure I was ok and that he is still in it to win it. I trusted this man with my life and he did not disappoint. If your in a tuff spot especially military, look no further this guy has your back. It is 1000% worth it at a very reasonable price.

Master of His Craft

LTC (Ret) Sean Mangan is a true master of his craft. The past 7 months have been a rollercoaster of emotion and uncertainty, however, I remained certain that I hired the best attorney for my case. When facing allegations that can ruin your career or life, Sean is the attorney to call. He kept me upda...ted throughout the entire process and provided valuable insight which helped keep my mind at ease during what is easily the most stressful time of my life. With over 20+ years of experience in military law, Sean Mangan's skillset is unmatched. I would recommend him to anyone in the military and would hire him again in a heartbeat.

Hire Sean Mangan Immediately!

Sean Mangan is a fantastic attorney. He is tenacious, thorough, and empathetic with his clients. I am an officer who was on a promotion list and was recently informed of a SHARP complaint. I contacted Sean and he was immediately responsive, informative, and reassuring. With the current political clim...ate, even a false SHARP complaint can be devastating to your career. I was understandably scared and worried. Sean helped me through the investigation process, engaging with the chain of command and law enforcement to advocate for my rights and my reputation. He helped demonstrate that the complaint was completely false and presented evidence showing that the “alleged victim” had previously given false sworn testimony in another matter. Through his intervention, the charges were dropped completely, the flag was removed favorably, and I received my promotion with the proper date of rank. As I said before, in today’s political climate, a SHARP accusation can be devastating. The military will do all it can to find you guilty even if you are innocent. The system is not designed to protect the accused, even if they did nothing wrong. I recommend hiring Sean immediately and allowing him to intervene proactively early in the process. He cares about his clients and seeing that they are afforded their rights. I highly highly recommend him!

Great Attorney

I’m a current police officer at an agency in Washington state. I recently faced an internal investigation with possible criminal implications. I reached out to several attorneys when my Union attorney was “unavailable” to represent me. Sean spoke to me for an hour. He was empathetic and provided ...me with excellent advice that gave me peace of mind going into my IA interview. After all of that, he even told me there’s no reason to hire him at this point and refused to charge me for anything. I’d highly recommend Sean to any LE or military person looking for representation.

The client's interests were represented to the full maximum potential. As an attorney, I would turn to Sean Mangan for tips on a wide spectrum of topics. I learned a great deal from Sean.

Highly recommend."
