I was hit by a car back in January 2019. From this, I went through an almost 3 year lawsuit. Bill made something that is beyond stressful and full of ups and downs manageable. For someone with zero prior experience dealing with such a matter, Bill made the whole process comfortable and easy to process. A great attorney that never tried to sway me one way or another. Always giving me that facts in the best way for me to understand everything as it happened, or how it could happen. Bill is as good an attorney, as he is a teacher through his guidance and education of a personal injury case. I was never left with a single moment of not understanding or thoughts that I wasn't in the best hands. Bill is the kind of attorney that actually cares about what's best for a client first and cuts no corners. There was no doubt that I was in the best of hands.

I am a Certified Financial Planner (CFP) and often have to refer my clients out to various specialty attorneys. Bill Coppol has worked with a handful of my clients on cases and they always had a great experience with tremendous results with the end of their case. Last year I personally had to use Bill to help assist our family with personal injury case with an auto accident. I was finally able to see Bill's work first hand, and he provided an incredible amount of help to us. I think Bill does a great job educating clients on the process of a personal injury case, and helping them make good decisions to ultimately provide best outcome and results for their lawsuits. From working with several of my clients and my own family, I have nothing but positive remarks to say about Bill and his team.

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.

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.
