About Nathaniel

Learn Nathaniel’s areas of practice.


In addition to being a general practioner at NS Wasserstein & Associates, PLLC, I own and manage Lindenwood Associates, a strategic development and restructuring advisory firm helping owners of small to medium sized businesses navigate through times of change, redirection, and financial distress. 


So I'm not your typical attorney because I've owned, managed and advised businesses for almost two decades. 


Although a general practicioner, providing many legal services, most of my clients are entrepreneurs with emerging companies.  And entrepreneurs require specialized legal services in many areas from owner relations, employment and customer issues, to competition and intellectual property protection.  


I'm a trustee on a number of non-profit boards both locally and nationally.   My other interests include fly-fishing, mixed martial arts and sprint triathlons.....but not all at the same time. :)

Nat worked with us on our wills. He was very patient as we had a complicated situation. He walked us through multiple options and provided a clear path forward. He was quick to respond and very easy to work with. We really appreciated working with him, and would highly recommend him to anyone.

I first called the office to find out more information about starting a business and after my consultation I was immediately excited and determined that this was going to be the lawyer and company I was going forward with. He quickly turned around my information and was able to deliver very quickly to me what I was needing for my corporation and educated me so I understood exactly what it all meant and helped me make very smart decision for my goals and my business. I would highly recommend Nat Wasserstein and Trust him for my future business needs.

Wise and Compassionate and Totally Comes Through
I highly recommend Nat Wasserstein! He is an amazing attorney who will come through for you in every way. I am so grateful that when faced with the daunting task of selling my family's business, we were able to engage him to help. As soon as he came on board, everything became instantly easier - and at the moment of truth when our deal was in jeopardy, he stepped up and totally saved the day by finessing the deal points on the spot and getting the deal done. He's wonderful at seeing the big picture, deeply understanding of what the other parties are looking for, and at the same time he's kind and compassionate, which is very valuable when you're navigating something so stressful. He helped us with so many aspects of the sale, from legal advice, to serving as our broker with potential buyers, to helping us figure out how to generate every possible document we might need and more. I definitely recommend him to anybody without hesitation.

I would highly recommend Nat for his professionalism and his knowledge. In fact, I already have. I found him to be very patient, willing and able to answer any questions that I had. He also has the ability to put his clients at ease while making difficult decisions about one's end of life.

An Outstanding Attorney
Nathaniel S. Wasserstein is an outstanding attorney. I am so grateful to Nat and highly recommend him to everyone. After my husband battle with cancer, he went home to be with The Lord. Nat helped me form a 501c3 foundation in honor of my husband legacy. Nat was professional, knowledgeable and caring. Nat fees are very reasonable and his experience, work ethic, genuine compassion far surpass any legal fee. Highly Recommended

Highly recommended experienced caring professional.
I needed a lawyer to handle several unfortunate damaging issues a person did against my business. Forgery multiple types, identity theft against 2 corporate names, and landlord issues. His confidence and calmness allowed me to focus on day to day business rather than the issues. As a small business owner that was priceless. Nat represented me in court, as well as mediation with success! Nat's extensive knowledge and extra steps have given me peace of mind knowing the businesses are protected including me. Excellent communication all times of day and night. From the first meeting with Nat he showed true concern and care as if i had been working with him for years. I highly recommend Nat , I am glad hes on my side.

One of the best!
Nat Wasserstein has been an absolute life-saver. As a new small-business owner, I didn't even know what to ask in terms of setting up my company. Nat took the time to explain every aspect of starting up a business; walk me through the process; explain the different kinds of business setups and advise me as to which one would be best for me; and answer all of my thousands of questions - all in language that I could understand. He responds very quickly to emails and phone calls, and is always pleasant and helpful - as is his staff. Hiring Nat was one of the best decisions I have made for my new business, and I would recommend him to absolutely everyone.

Nathaniel Wasserstein provided sound legal representation and made it easy to accomplish my legal needs (setting up a business). He was fast, efficient, and didn't waste time "wracking up hours."

Great experience!
I found Nat through the group legal plan for my job when I needed to create a Will, Health Care proxy and power of attorney. Nat was a pleasure to work with. He was very knowledgeable, personable, and took the time to call me to answer all of my questions and incorporated my feedback (thru multiple iterations) to make sure everything was to my liking. He was easy to reach thru email, very responsive and provided great input (vs. just checking the boxes) throughout the process. I will definitely consider him for any future legal needs!

Outstanding Attorney, and cost efficient
I have used Mr. Wasserstein as my lead council for the last 5 years. He is extremely bright, thoughtful, efficient, innovative in his thinking and very cost-conscious. As the CEO of a start-up, I couldnt imagine a better attorney to have in my corner.

Wonderful, knowledgeable , kind and Professional
I went to Nathaniel for a consultation when starting up an all natural beauty product line. I needed advice as to what's legal, what I should and a should not do, do I need to be licensed to start this type of business, and many other questions only a knowledgeable lawyer can answer. Not only did he answer my question patiently and thoroughly, he went beyond that and gave me advice, couching, sent me reading materials, and was willing to work with me every step of the way. He is kind, patient and knows the law very well. He also genuinely believed in me, and gave me a huge boost of confidence to become an enterpeneur. I honestly couldn't have started this business without his help, and I highly recommend him to anyone who needs legal consultation when starting a business.

HIGHLY Recommended!
I initially engaged Nat's services for a copyright infringement issue which he efficiently and thoroughly resolved. As a result of his expertise, my work was recognized and my profits greatly increased. A year later, I returned to him for counsel regarding a large contractual agreement. He negotiated compensation at a higher percentage than what was originally offered. Nat's business and legal experience paired with his creative entrepreneurial spirit were a perfect combination for me to achieve both my legal and financial goals.

On Point
Contacted Mr. Wasserstein through a referral service. Explained my situation, he offered suggestions on the best course of action. I felt comfortable with his knowledge of my pending issues. I retained him to pursue a amicable resolution to my situation. He took made a couple of calls and negotiated me a deal that I was very pleased with. He kept me in the loop every step of the way. I would highly recommend him to anyone that has a debt collection issue.
