Dennis Shlionsky is a Partner with the firm’s Accidents/Personal Injury Practice Group.

Born, reared, and educated in the Garden State, Dennis has spent his entire career representing ordinary people injured through no fault of their own. His practice handles personal injury cases of every kind and complexity across all 21 New Jersey counties, ranging from car, motorcycle, truck and rideshare accidents to falls on public or private property, Tort Claims Act cases against government entities, broker malpractice, wrongful death claims, and other catastrophic injury cases.

Dennis recognizes the value of a timely resolution, but he does not hesitate to take a case to trial when the circumstances demand it – an approach that has produced more than $50 million in recoveries against insurers and corporations that refuse to fairly compensate families affected by life-altering circumstances.

He takes pride in his caring, empathetic approach – building trusted relationships with his clients and their families while working diligently to help them obtain the compensation they deserve. With extensive experience guiding people through the legal system, Dennis remains responsive and accessible to his clients, answering questions, providing regular updates, and offering support at every stage – from initial consultation through treatment and final resolution.

Dennis’ results and advocacy have earned consistent recognition from the legal industry. He has been recognized in Best Lawyers: Ones to Watch in America® in 2023, 2024, 2025, and 2026 in the Personal Injury Litigation – Plaintiffs category. He has also been listed as a “Rising Star” by New Jersey Super Lawyers from 2019 through 2026.

Dennis was included in ALM’s 2022 Northeast Top Verdicts & Settlements list for his work on a motor vehicle settlement in Bergen County and has been awarded the AVVO Client’s Choice Award from 2021 through 2025. He was certified as a member of the Million Dollar Advocates Forum in 2026.

In August 2023, The New Jersey Law Journal published his article, “The Evidence Speaks for Itself: A Proposal for the Amendment of Rule 4:14-9.”

Dennis began his career as a General Equity Law Clerk to the Honorable Margaret Goodzeit in the New Jersey Superior Court for Warren, Somerset, and Hunterdon Counties. He went on to practice at established New Jersey litigation firms before joining Einhorn, Barbarito, Frost, Botwinick, Nunn & Musmanno. He is also a former court-appointed mediator, resolving 96% of the matters he mediated.

Having lost his mother to lymphoma as a teenager, Dennis volunteers actively for The Leukemia & Lymphoma Society. He has been recognized by the Eric Neisser Public Interest Program for contributing to several pro bono ventures, and he has provided pro bono bankruptcy and other assistance to New Jersey and Minnesota’s underrepresented poor and low-income communities through the Morris Stern Bankruptcy Project and Justice Foundation’s Criminal Expungement Clinic.

Client Testimonials

“I can’t thank Dennis Shlionsky enough for the way he fought for my mother and me after our car accident. We were on our way home from work when we got caught in a crash caused by a car and tractor trailer. From day one Dennis treated us like family and took great care of my mother who is legally blind. He listened, he cared and most importantly, he delivered on exactly what he promised us.
The insurance companies tried to downplay what we went through, but Dennis never backed down. He navigated a complicated case with multiple lawsuits and made sure we got the settlement we deserved. Thanks to him, we can finally move forward. If you need a lawyer who actually cares and knows how to win, Dennis Shlionsky is the one. We really appreciate everything you have done for our family.” – Rashon Hilton

“I was introduced to Attorney Dennis Shlionsky by my friend, who had worked with him before. My situation was challenging after an accident while testing/working on my uninsured and unregistered motorcycle. Another driver hit me out of nowhere, and I ended up flying off my bike. With no collision coverage and the other driver’s insurance holding me 40% responsible, I was left with a totaled motorcycle, medical bills, and an injured shoulder. Dennis and his team, including Danielle and Janet, were with me every step of the way, explaining the process, keeping me updated, and ensuring I felt supported. In just a few months, I secured a six-figure settlement for both my injuries and my motorcycle, far beyond my hopes. If you ever find yourself in a similar bind, I can’t recommend Dennis Shlionsky enough.” – Harold Vivas

“This was my first time hiring a personal injury lawyer, and I would like to leave a review regarding my experience. I was recommended to Dennis Shlionsky by another friend of mine who is also a lawyer. He took my call on the weekend, and I explained the situation. While riding my motorcycle in Weehawken through an intersection, a driver turning left in front of me caused me to hit her and flip over the car. The driver claimed she had the green light, and the insurance company blamed it on me. They would not cover my brand new chopper or pay me for my injuries. But Dennis shut them down.
In a couple of months, I was reimbursed in full for my bike and received all of the money from the other driver’s insurance. He was absolutely amazing and kept me updated as this was my first time through the process. If you were injured in an accident, Dennis is the best. I recommend him without reservation!” – C.L.

“I want to share my experience, but I have language barrier. I had an accident. While I was delivering, someone hit my car. It was a surprise. I didn’t see too big damage to my car, so I thought everything was fine. But I still decided to go get treatment for my injuries. I went to therapy for a few months. It was a hard time for me, but I knew I needed to take care of myself. During this time, Mr. Shlionsky helped me a lot. He always took my calls, even on weekends, to make sure I didn’t have any stress. He worked very hard for me. I feel so humbled and grateful for everything he did. Thanks to him, I was able to get a good compensation. This support really means a lot to me. I want to say a big thank you to Mr. Shlionsky. I am very thankful for all he has done for me. His help changed my life in a big way. Thank you, Mr. Shlionsky!” – G.K.

“Thank you, DENNIS SHLIONSKY and DANIELLE! This is the second time Dennis represented me, and I couldn’t be more thankful. Right when we were about to settle my first case, I got into another minor accident that made my neck pain even worse. The insurance company tried to brush it off as a simple fender bender, but Dennis didn’t let them get away with it. Even though I had surgery after the first accident and the MRI showed my herniation had shrunk, Dennis fought tooth and nail to make sure I got every dollar I deserved. Dennis isn’t just an incredible lawyer, he’s a genuinely good person. He listens, cares, and follows through on everything he promises. There were times I needed to reach him on weekends or late at night, and he always picked up the phone, no questions asked. He made sure my medical bills were taken care of and never let the insurance company push me around. Dennis truly saved the day and got me all the money I was owed. If you need a lawyer who’s relentless and also has your back, Dennis is the one. He’s hands-down the best.”- E.R.

“I’m really grateful for Dennis Shlionsky and his amazing team! I was stopped at a red light on US 1 in North Brunswick when a chain-reaction crash ended up with my car getting hit. It was a mess, but Dennis and his team took care of everything. They explained the whole process clearly, answered all my questions, and made sure the responsible parties were held accountable. Dennis and his team worked hard to get me all the compensation available. If you need a smart, caring lawyer with a great team, I highly recommend Lawyer Dennis Shlionsky!” – Arthur W.

“Dennis Shlionsky and his team at Einhorn Barbarito were a game-changer for me. I was overwhelmed after being injured in a car accident last summer in Manville, NJ. Luckily, my employer, a law firm, recommended Dennis – what a recommendation that turned out to be! Dennis didn’t just fight for me against the insurance company’s blame game on my old neck and back injury; he showed me empathy through the entire process. He made himself available even on weekends, which was a lifesaver for someone juggling recovery and work. His team, including Valentina and Danielle, were equally amazing. I can’t thank Dennis and his team enough for making a tough time more manageable. Thanks to Dennis, I not only received all the compensation I deserved but also had peace of mind knowing that all my bills were taken care of. If you’re looking for a lawyer who truly cares and gets results quickly, Dennis Shlionsky is the one – I’ll recommend him to my friends and family without hesitation.” – Christine Piccirillo

“I am so thankful to have had Dennis Shlionsky as my attorney following my terrible car accident. Dennis exudes professionalism with what I call a bite! He worked so hard to get me the care I needed and was available to answer any and all questions I had throughout the process. Thank you Dennis and Danielle for fighting for me.” – Lori Pastula

“I’m an attorney (look me up), and when I was hit by a car, I went to Dennis Shlionsky. Dennis was trained as a commercial litigator before he got into PI, and he runs circles around his adversaries. He also helped me navigate some seriously difficult insurance issues after I had been treated by a dozen physicians (some out of network). Listen to whatever ad or billboard you want, but… IYKYK.”- Pierre Chwang

“The team at Einhorn Barbarito were truly exceptional. Each member, from Dennis Shlionsky, an outstanding attorney, to his team, Jasmin, Valentina and Danielle, exudes professionalism, warmth, and a genuine commitment to their clients’ well-being.  I injured my shoulder in a car accident last summer. I was recommended to Mr. Shlionsky by a friend and his dedication went above and beyond mere legal representation. He not only went head-to-head with the insurance company and got us all of the monies available, but was also a compassionate listener, who offered invaluable support and guidance during the entire process and moments of uncertainty. His determination to fight for my interests, even when I felt overwhelmed, was truly remarkable. His team, Jasmin, and Valentina, were equally instrumental in my journey, consistently demonstrating responsiveness and patience as they addressed my inquiries and concerns. Their willingness to take the time to explain complex matters eased the burden of navigating through a challenging ordeal. Words cannot adequately express my appreciation for the positive impact they’ve had on my life during this difficult time.”- Dayana Bustamante
