Just shy of 2 years ago, I was in a terrible motorcycle accident that left me in a coma for 5-6 days. I suffered countless life-threatening & serious injuries, and it's truly a miracle that I survived. From the moment I hired Mattiacci Law LLC to represent me, John, his paralegal Kristin and the entire team worked day and night to fight for me, when I didn't have the strength or ability to fight for myself. Now, just one month shy of the 2 year anniversary of my accident, and the legal battle is over! I am finally able to focus all of my attention and remaining strength on my health and recovery, all thanks to Mattiacci Law LLC!!To John, Kristin and the rest of the team, Thank you so much for all that you have done for me. This was my first time dealing with something of this nature, and I could not have been more impressed and grateful. Thank you.If you are in need of a lawyer and firm to represent you, and you haven't considered Mattiacci Law LLC yet, it's time you should. John and the entire team will work endlessly to ensure that the battle is not over until it's won! I am able to finally live peacefully again, with a smile on my face because of Mattiacci Law LLC!

I couldn't be happier with my experience with Mattiacci Law. John was amazing with handholding us through the process during an extremely stressful time for our family. He and Kristin treated us with compassion and respect. I appreciated the robust discussions on next steps and that we really felt like they were partnering with us on every decisions. Personal injury cases can be very labor intensive with regards to gathering documentation and working with insurance companies etc and I really felt like Kristin and John relieved that load from us so we could focus on the things we needed to get healthy. The expertise we received was invaluable and I always felt like they delivered information in a way that I could understand easily. I will always be so grateful for the support and would recommend Mattiacci Law to any of my family or in friends because I know they would be in great hands.

Our Approach

We don’t settle for anything less than the best

Most cases don’t make it to trial, but we prepare for it regardless. Insurance companies can use many tactics in an attempt to cheat you out of the settlement you deserve, so sometimes, escalating to trial is necessary. In the event of a trial, our personal injury attorneys know how to handle the insurance companies and rigorously defend your rights.

Meet Managing Attorney John Mattiacci

For more than 16 years, I have represented clients who were paralyzed, brain-damaged, permanently injured, or killed. I pride myself and am honored by the many opportunities I have had to help families pick up the broken pieces and put their lives back together after devastating injuries, accidents or death.

Service is at the heart of my Philadelphia personal injury practice. When you work with me, you are family, and I fight for you like you are one of my own. Not all law firms offer the dedicated attention that myself and my associates can, and we wouldn’t have it any other way.
