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.

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.

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.
