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.

Sweeney Merrigan Law—and especially our attorney, Erin—went above and beyond for our family during one of the most difficult times of our lives. Erin handled my daughter’s personal injury case with exceptional skill, care, and dedication. From the very beginning, Erin treated us like more than just clients—she listened, guided us every step of the way, and truly understood what our family was going through. Her professionalism and relentless commitment to achieving justice were evident in everything she did. Thanks to Erin and the entire Sweeney Merrigan team, we felt supported and protected throughout the entire process. She fought tirelessly for my daughter and secured a result that will have a lasting positive impact on her future. We are forever grateful for Erin’s compassion, expertise, and unwavering advocacy. I would highly recommend Erin and Sweeney Merrigan Law to anyone in need of a personal injury attorney who truly cares about their clients and delivers outstanding results.

I had a great experience working with Erin from Sweeney Merrigan! Erin was great at communicating with me throughout my injury case process. She made me feel very comfortable and informed. Heather was also easy to connect with when they needed more information or if I had questions. Erin made sure I had all the proper medical documentation to accurately build my case. I trusted her professional judgment with how to proceed during the back and forth settlement with the insurance company and was satisfied with the amount of money I received from the case. I highly recommend working with the Sweeney Merrigan team!
