Criminal Defense Attorney
Sean is a great lawyer. Very professional, knowledgeable, honest & straightforward. He gives you the facts good or bad & the options on how he can handle the case in your best interest. He has always responded to my emails & phone calls immediately regardless of what time of day it was. I have dealt with many lawyers over the years & as far as I'm concerned Sean is one of the best. After my case was finished I was so happy I purchased a $100 gift card to a fine restaurant in DC for him & his wife. I have never done that for any attorney before. I think it speaks for itself. Highly recommend.

Mr. Farrelly represented me on a DUI case that originated back in September of 2012. Mr. Farelly did an exceptional job throughout the entire journey. The case lasted a long term of 21 months but Mr. Farelly, with his abundant experience and exceptional knowledge as an attorney, made me feel that I was in good hands. He did an amazing job the entire time that I was in court. He communicated clearly and throughly all the pros and cons about my case. He is a sincere and honest attorney that will work with you no matter what the situation will be. He is timely and is always ready. My case finally ended on May 22, 2014 when a jury comprised of 12 citizens of the District of Columbia found me NOT GUILTY of driving under the influence after only one hour and a half hour of deliberation. I strongly recommend Mr. Farelly to everybody, you will not regret choosing his services.

Criminal defense Attorney | Sep 07
Relationship: Friend
"Attorney Sean Farrelly is someone I have known for over twenty years and is a close friend of mine. But he also possesses a combination of skills that few attorneys have - whether they are young or old. He's naturally very intelligent and as quick on his feet as they come, but also well-read and disciplined to learn everything he can about the practice of law. He can explain complex and difficult legal situations to clients in plain english, while also explaining nuances of the law in detail to police officers, prosecutors, defense attorneys, and judges. He's also somebody that will stick by your side and go the extra mile when few others will. I'm proud to say that Sean has been a great friend who is more like a brother. But I also sincerely endorse him as a criminal defense attorney who will truly care about your situation and fight for you every step of the way."
