At Mattiacci Law, our Philadelphia personal injury lawyers strive for:

24/7 Service

Whether it’s one in the morning or one in the afternoon, you can expect to connect with Mattiacci Law. Winning is important, but keeping you up-to-date on your case is of equal importance to us.

Cost-Free Until We Win

We are so confident in our ability to achieve a settlement that we practice on a contingency basis. That means that you don’t pay us a dime until we win your case.

Results Driven

Our results speak for themselves. We pride ourselves on the results we obtain for our clients.

You can place your trust in us.

Some of the worst times in our lives require us to seek out an attorney. Courts and Attorney's can be intimidating, even frustrating at time. Having John on our side was literally like having my "big brother" come out to stomp the bullies who hurt my family. He was professional, thorough, honest, trustworthy, responsive, and always had my back. He was very personable, and always felt more like my best friend then my attorney. Being able to find a good honest attorney in this day and age can be difficult. I was truly blessed to have found John. I will always be thankful for the work he did, and hope that some day maybe in some way I will be able to return the favor. If youre looking for an attorney, look no further.

John helped us with our lawsuit, and I can't thank him enough for all he has done for us. He is very smart, professional, knowledgeable, caring, and dedicated. Kristin, his paralegal, is also very prompt, sweet and helpful. John is very pleasant to talk to, and just a great guy. I am so glad we selected him to represent us, we put our trust in him, and he did a fantastic job. I highly recommend him to anyone! Thanks, John!

I had the pleasure of working with Bill Coppol for just under 3 years. From the beginning of a case until resolution, Bill always prioritizes his client’s best interests. He is highly respected by his co-workers and clients. He is very knowledgeable and one of the top litigators I’ve ever worked with. I have been working as a paralegal for over 10 years and Bill is by far one of the hardest working attorneys I know. If he is handling your case, you can be confident that he will deliver positive results.

I was referred to John by an attorney relative after I suffered a serious fall. John and his staff guided me through my case with compassion and professionalism, and they always treated me with the utmost kindness. They kept me informed of the status of my case throughout the process and were very supportive. I was very happy with the final result. I would recommend John and his wonderful staff to anyone.

I had the unfortunate experience of being in a car accident and I couldn’t have had a better person to represent me than John Mattiacci. At a time when I needed guidance the most, he was there every step of the way. He not only cared about helping me, he cared about how I was feeling. He returned calls promptly and answered any question I had. It was a pleasure working with John Mattiacci and his firm. Thank you for all you did for me.

I had the unfortunate experience of being in a car accident - hit at a red light by a kid texting behind me. He never even hit the breaks. I have never sued anyone in my life - so this was a new situation. I can't tell you how safe and confident I felt with John Mattiacci representing me. He was always in touch - handled every detail which left me able to recover from my surgery. I was very pleased with the settlement. If I could give 10 stars I would.

John, Jim, and Kristin are three of the nicest people I've ever met and they all care so much. They were all very responsive whenever I reached out and always kept me up to date with what was going on, even when things were slow moving. Very understanding, motivated and passionate as well.

After I was in a serious accident a close legal friend referred me to John Mattiacci and it turned out to be he best advice I ever received. John was not afraid to battle the insurance companies to get me my due compensation. He tirelessly went head to head with these large companies and refused to let them bully me. I would refer Mattiacci Law to anyone, in fact I referred a family member and they too were very pleased.

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 use many tactics in an attempt to cheat you out of the settlement you deserve, and sometimes, escalating to trial is necessary.

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 or death.

At the heart of my practice is service. 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.
