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.

Primarily working with Heather and Erin, the Sweeney Merrigan team stayed with me through a long and unique case. It was my first experience needing a legal team. Heather and Erin could always explain where we were in the process and what my options were along the way. I don’t want to get hurt again, but if I do, I know who I’m calling.
