John J. Leppler is a different kind of attorney. In a Baltimore legal landscape where megafirms collect clients and run them through the legal assembly line, John provides a personable, small-firm atmosphere where the lawyer you hire is the lawyer you work with on all aspects of your case. That’s just John.

John never turns his back away from the underrepresented and disenfranchised, who are typically ignored by the mega-firms. That’s why he created Leppler Injury Law, to ensure everyone has access to the rights the legal system affords – regardless of your background or occupation. As a result, John’s clients are not afraid to call him directly with any legal questions they may have, and he welcomes the opportunity to be available for them whenever they need him.

John has had a lifelong love of sports and studied business and sports management in college.

During his first year of law school, John’s passion of study shifted from advocating for athletes to advocating for the injured in need of quality representation to stand up to the insurance companies. He’s seen first hand, more times than you can imagine, insurance companies taking advantage of the injured and attempting to settle claims for far less than what is fair and right. He uses the principles from his sports background to take on the insurance companies – preparation, unwavering focus and a relentless attitude to win.

When it comes to fighting for his clients’ rights, nobody is more serious than John. He takes your legal issues personally and will never stop fighting to get you your best possible outcome. John has always liked to win, and today he wants to win for you.

After a good time searching for the right lawyer to handle my wife's accident case we settled on Attorney Leppler. He was so thorough and diligent in fighting the big insurance companies that they 100% caved after initially denying us without Attorney Leppler on our side. From the way he talks and updates us periodically to looping us in on his attack strategy you can definitely tell he is totally on our side fighting for us. Really the positive Google reviews about him are not hype, Attorney Leppler is the real deal.

Attorney Leppler was really helpful from the very moment I contacted him. He took his time to hear all my fears and complaints that I had and he was able to walk me through the entire process and how long the process may likely take. He was very patient with me by taking this time to answer my numerous questions and explaining them in a very comprehensive manner. He regularly called me to give me updates on the case and what to expect in regards to some of the actions he was taking, an act I was really really appreciative for. You could see from the way that he handled my case that he was truly interested in helping me get a good resolution. I can confidently say that choosing Attorney Leppler was a very good decision. Trust me he will fight for you vigorously.

Mr. Leppler and his legal assistant Barbara were professional, prompt, and friendly. 12/10. Barbara even helped to fill out HIPPA forms after the accident. Mr. Leppler was on top of every part of the case. Thank you again the both of you!

After being in an accident in February, I thought having to deal with a lawyer after the fact would be stressful. But working with Mr. John was far from that. He made me and my family feel comfortable throughout the process. He and his team (including Ms. Barbara) were extremely nice, communicative, and reliable. With this being my first time having to rely on a lawyer, I'm grateful that this was the experience I had with one. Thank you to Mr. John and his injury law firm, 100% recommend!
