I have been very pleased working with Sweeney Merrigan Law and in the result they obtained in my lawsuit. I found them very professional, responsive, and easy to contact. I would definitely not hesitate to recommend them to anyone looking for a top notch law firm.

Attorney Erin McHugh and her team at Sweeney Merrigan Law did a outstanding job on my case. They are very professional, responsive and most of all genuine! If you need any help, I highly recommend Attorney McHugh! She will get it done! Thank you so much for helping me! - Chief Michael Abrajano, U.S. Navy

There are thousands of attorneys. I am sure they are all good. However, if you want an attorney that is honest, caring, genuine and really takes the time to listen to you..... Sweeney Merrigan is who you want. Everyone in the office is professional, caring and understanding.

Highly recommend this amazing team, especially Erin and Alexa! A couple months ago I suffered a horrible, painful accident that required surgery and multiple hospital visits. While I was in recovery, Erin and Alexa took care of EVERYTHING! Erin and her team, were super responsive, thoughtful and kind enough to answer all my silly questions throughout the process. I had never experienced an personal injury accident before, so having a team who was thorough and willing to walk me through the process meant a lot to me. They took care of the paper work, legal jargon, and advocated for me, so I can completely focus on getting better! If you’re looking for representation I’d encourage you to reach out to the team, they are knowledgeable, efficient and caring!

I recommend Sweeney Merrigan to anyone looking to for legal help and a dedicated team of aide that will prioritize your needs and the severity of your injuries. Erin McHugh was my attorney she always communicated effectively in a timely manner and was always concerned about my health or if I had an problems not to hesitate to reach out. Thanks Erin and Team for everything!
