Serious injuries can change your life in an instant. When that happens, having the right legal team matters.

Our personal injury attorneys represent clients throughout Philadelphia; Conshohocken in Montgomery County; Medford, New Jersey; and Camp Hill, Pennsylvania providing focused, trial-ready advocacy for people harmed by negligence. We understand the physical, financial, and emotional toll an injury takes, and we work closely with each client to pursue accountability and meaningful compensation.

Philadelphia’s courts, insurers, and defense firms are familiar territory for us. From Center City to South Philadelphia, North Philly, and the surrounding suburbs, we bring deep local knowledge to every case. That experience allows us to anticipate challenges, move cases efficiently through the legal system, and position our clients for strong outcomes. We don’t rely on shortcuts or quick settlements that fail to reflect the true impact of an injury.

Our work in Conshohocken in Montgomery County, Medford, NJ, and Camp Hill, PA reflect the same commitment. Many injury cases involve regional employers, property owners, healthcare providers, and insurers with significant resources. We prepare every case thoroughly and strategically, whether it involves a motor vehicle collision, workplace injury, medical negligence, or a catastrophic accident. If a case requires litigation, we are ready to take it to court.

What sets our firm apart is the level of personal attention we provide. Clients work directly with experienced trial lawyers who are accessible, responsive, and invested in their cases. We take the time to explain the legal process, answer questions, and help clients make informed decisions at every stage. You will always know where your case stands and what to expect next.

As Philadelphia personal injury attorneys, we believe trust is earned through preparation, transparency, and results. Our goal is not just to resolve claims, but to advocate for people when they need it most.

At Groen Strokoff O’Neill Trial Lawyers, we deliver strategic, informed representation designed to guide clients smoothly through each stage of their case—from insurance claims through courtroom litigation. Our attorney’s services include:

Every case begins with a careful review of the facts. An attorney will listen to your story, assess liability, and evaluate the strength and potential value of your claim. We then outline your legal options and develop a strategy tailored to your specific circumstances and goals.

A successful personal injury claim depends on strong, well-documented evidence. Your lawyer will collect and analyze key materials such as accident reports, photographs, video footage, medical records, and witness information. This process helps clearly establish what happened and how your injuries have affected your life.

Insurance companies often attempt to resolve claims for less than they are worth. Our attorneys advocate firmly on your behalf, using evidence and legal analysis to push for a fair and meaningful settlement. We focus on securing compensation that reflects the full impact of your injuries, losses, and future needs.

When a fair settlement isn’t offered, we are prepared to take your case to court. Our trial lawyers develop a clear litigation strategy, present compelling evidence, and hold negligent parties accountable before a judge or jury.

Personal injury claims involve extensive paperwork and deadlines. Your attorney handles all filings, correspondence, and required documentation, ensuring accuracy and compliance while reducing stress. This allows you to focus on recovery while we manage the legal details.


Our trial lawyers are dedicated to achieving justice for negligence in medical malpractice cases, wrongful death, auto accidents, nursing home abuse, workplace injury cases, and more.

Many injured victims hesitate to contact a Philadelphia personal injury lawyer because of concerns about legal fees. After an accident, medical bills, lost income, and other financial pressures can make hiring an attorney feel out of reach.

Personal injury cases are handled on a contingency fee basis, meaning there are no upfront costs. Instead of hourly fees, the attorney is paid a percentage of any compensation recovered through a settlement or court verdict.

If no compensation is recovered, the client owes nothing for attorney’s fees. In other words, there is no cost unless the case is successful. This allows injured individuals in Philadelphia and surrounding areas to pursue their claims without financial risk.

This fee structure also ensures that your attorney’s interests are aligned with yours and are focused on achieving the strongest possible outcome while you focus on
what’s important.


Our Philadelphia personal injury lawyers have a record of results in serious injury cases, including significant verdicts and settlements achieved through strategic litigation and negotiation.

When I reached out to Max Goldberg after my car was totaled by another driver and my elderly mom was severely injured, I was beside myself. He calmed my fears and handled every detail with professionalism and kindness. He was patient with my many questions, handling both of our case with compassion. I put my trust in Max and he did not let me down!

I honestly didnt know what to expect when I had to seek legal council. I was fortunate enough to have Bill Coppol as my lawyer. From day one Bill was thoughtful, transparent and caring. I never felt for one moment that he did not have my best interests at heart. I highly recommend assure you that you will be in good hands. Also shout out to an unsung hero. Mike is a paralegal here and he was with me for select appointments and was always on top of communication and information gathering.

We are incredibly grateful for the outstanding work Justin Groen did on my families behalf. From the very beginning, he was professional, compassionate, and truly committed to our case. He took the time to explain every step of the process in a way that was easy to understand, which gave us a lot of confidence during a very stressful time. His attention to detail, strong knowledge of the law, and dedication to achieving the best possible outcome really stood out. We always felt like our concerns were heard and that our case genuinely mattered to him. Communication was consistent and clear, and he was always responsive whenever we had questions. Thank you Justin and the entire GSO team for all of their hard work and expertise, our case was handled successfully, and we couldn’t be more satisfied with the outcome. We highly recommend Justin to anyone in need of a skilled and trustworthy attorney. He is the absolute best in the business!!!
