Celebrating Over 50 Years of Service

About Us

Nusbaum Stein, P.A., was established in 1968 as a full-service law firm. Lewis Stein, one of the firm’s founding fathers who is pictured in the middle of the photograph on this webpage, developed a personal injury and medical malpractice plaintiffs’ practice which, over the course of his fifty year career, became one of the most successful practices in the State of New Jersey.   Lew passed away in July 2019 at the age of 83, and we will forever miss him.  Indeed, Bob Kobin and Steve Loewenthal, pictured in the photograph surrounding Mr. Stein, are honored to have tried cases with Lew and followed in his footsteps by continuing to successfully prosecute personal injury and medical practice lawsuits on behalf of injured individuals.

Lewis Stein always fought for justice and the best result for his clients and was extraordinarily successful.  As Lew slowed down over the past ten years, that passion and track record has not missed a beat since Bob and Steve have both developed their own extraordinarily impressive record of successfully trying and settling cases.   Having been located in northwest Morris County for over fifty years, our firm is especially sensitive to the needs of residents local to that area.   In addition, however, both Bob and Steve handle cases throughout New Jersey and New York City, where Steve started his career and continues to practice.

In short, Nusbaum Stein, P.A., is known for providing small town caring and attention with big city sophistication. Take the time to explore our website and familiarize yourself with who we are and how we can help you. Most importantly, do not hesitate to contact us with any questions or a free consultation.

When we started one of the things we said was “People First” and that had a lot of meaning to us because it meant the clients come first.

I retained attorney Steve Loewenthal to handle my personal injury case. Prior to our consultation, I was nervous  and still  unsure about what to do. Steve explained  the law, my options, and addressed all my questions or concerns about going forward. He’s an extremely knowledgeable attorney  who acts in a professional, respectful, and kind demeanor. He is direct and honest, does not make any ridiculous promises, or show any sign of unethical behavior.  Before  the depositions,  he explained the process, took the time to calm my concerns/fears, but most importantly, instructed me to tell the truth. I am aware of some of the negative stereotypes assumed about personal injury attorneys; however, Steve exhibits NONE of these negative qualities.

If you are a sports fan, you will love his office! His has an amazing assistant who was also very helpful! I did not call often but when I did, she knew who I was and exchanged pleasantries. With integrity and expertise, Steve succeeded in effectively handling my case. I do not share my experiences often; but in this case, Steve Loewenthal definitely earned my trust, respect, and my recommendation!

A Diamond in the Rough!

Mr. Loewenthal represented me in a civil case. From the initial consultation to the settlement, Steve provided the most professional, knowledgeable and considerate level of service. Steve kept me informed every step of the way and took his time to explain each new development in the case.

Steve’s experience gave me confidence from the outset the case would be handled with expertise. He was able to coordinate between all parties involved and his negotiating skills resulted in a most favorable outcome. His staff was a pleasure to deal with and were very accommodating. Steve and his office went above and beyond and he comes with my highest recommendation. Thank You, Steve, for everything you did in handling my case.

Highly Recommend

Mr. Loewenthal took my automobile personal injury case after 2 other law firms turned me down because of car insurance reasons that couldn’t get me a settlement. In NJ, you only have 2 years after your date of accident to pursue personal injury damage. I went to Mr. Loewenthal with my case close to 3 months before the 2 year deadline to sue. He walked me through everything that was going to happen, assured me that we have a case and worked hard on my case and met the deadline to sue. When Mr. Loewenthal called me withe settlement number, I almost fell off of my chair. He got me way more than I thought was possible, for I thought I was getting nothing because of the other lawyers turning my case down. Needless to say, Mr. Loewenthal is a “Jackpot!” lawyer and I recommend him 101% to anyone who wants a real lawyer.
