I had an excellent experience with Sweeney Merrigan Law Firm, especially Carleen Mullally. Carleen was professional, responsive, and always took the time to explain everything clearly. She handled my case with care and skill, and she ultimately helped me win my lawsuit. I’m extremely grateful and highly recommend her and the firm.

I contacted Sweeney Merrigan after being completely failed by my first lawyer. I was injured when a truck blew a stop sign… had to go through a year of pt and ot and missed work. The first lawyer dropped the ball so badly that even my own insurance company suggested firing him. I found Sweeney Merrigan and what a difference!! Right off the bat they got to work and were so thorough and helpful. I was thrilled with the quality of work and the outcome of my case and they were such nice people too. I really feel lucky that I came across them and cant say enough praise about them.

Erin and Heather from Sweeney Merrigan Law worked tirelessly so I didn’t have to. Anytime I had a question it was throughly explained and every time I called the phone was answered. They were up front and honest from the start I couldn’t have asked for more from them. Id recommend them to anyone and if I ever need an attorney again they will be the first call I make.

Hi my name is Amanda back in 2023 I was a passenger involved in a serious car accident. My husband reached out to several law firms and he decided to go with Sweeney Merrigan. When he first spoke to them he was speaking with Ryan who quickly decided our case was better for Matthieu. Matt has work endlessly for the last 2 years with our case. He was understanding, So nice, they even sent me flowers on my big surgery day! They are so sweet! If you’re looking for a team of lawyers who have your back and won’t stop until you get justice I highly recommend Sweeney Merrigan Personal Injury Lawyers. Matt worked very hard and never gave up and always answered my call or texts he is amazing at what he does. Thank you so much Matt and the rest of your team at Sweeney Merrigan for not giving up and for taking our case ❤️ Amanda ????

I met the Sweeney Merrigan team at a local fair and they were very friendly and welcoming. They were handing out free backpacks and taking time to talk with people in the community. Really appreciate their generosity and support—it left me with a very positive impression of their firm.
