Client Testimonials

The Lawyer Everyone Should Have!

I had an issue come up and was given Jonathan’s number. I gave him a call and he immediately got to work (even though he was out of the office). We setup some time to meet in his office, discussed what was going on, and from that point forward he not only worked his magic, but was able to explain what might happen, what would happen, and what options we should think about before they happened…

Jonathan Sack Delivers !

I engaged Jonathan and his team to assist with an age and gender discrimination situation at my former firm. Jonathan was responsive and supportive. He was with me every step of the way, and were ultimately vindicated. Jonathan is a straight shooter. He brings decades of experience to the table. I am thankful that he was on my team and I highly recommend him.

Amazing !

Johnathan Sack is a kind and generous attorney. He answered all my calls while he was on vacation with his family and made me feel at ease with my case. I would go to him for any matter big or small as him and his team can handle it.

Against Large Financial Services Firm

Represented me against my former employer (a large bank) in a retaliation and discrimination claim. Quietly resolved the matter by negotiating a very generous severance package representing multiple years of my annual compensation. Very knowledgeable and capable attorney. Developed and executed a result-oriented strategy that yielded quick and confidential results

You Want Him On Your Side

I was terminated from my job at an investment bank, and was treated unfairly. I went to several employment attorneys, and they all refused my case because there was no “smoking gun.” Jonathan was able to get me what I deserved. His best skill is good-old-fashioned tenacity. You want him on your side. Period.
