I consulted with Jonathan as I needed help extricating myself from my previous employer. He was extremely responsive, gave actionable recommendations, and was strategic on how the negotiations would play out with and without litigation. While I did not pursue a lawsuit route, he prepared me for th...e implications of litigation. I highly recommend him if you need a strategic advisor.

Jonathan has been a tremendous help in navigating the legalities of my startup business. His no nonsense approach was instrumental in achieving the necessary contractual framework for my business. Jonathan is extremely efficient and helped achieve these goals while keeping billable hours to a minim...um. I highly recommend him.

After being wrongfully terminated from my employer I interviewed five counselors to represent me. I am very fortunate to have chosen Jonathan. Jonathan was a zealous advocate for my cause and produced impressive results in an efficient manner. The personal touch and care for my situation was unexp...ected. Even after we settled, Jonathan went out of his way to help and advise on career issues. I have worked with many lawyers in my career and I have yet to see one that fights for a client like Jonathan.

Mr. Sack was at all times forthright, direct and concerned about my case. I was laid off due to Covid 19 and Mr. Sack negotiated with the Human Resources Department at my institution for a greater severance. While this was ultimately unsuccessful I have the utmost faith in Mr. Sack for his knowledgea...ble and realistic approach to my situation. I consider my association with Mr. Sack a success and I would hire him again and I recommend him highly.
