Jonathan Sack is the “real deal”

Jonathan Sack actually listened to us. He took the time to understand the inequity of our situation. He was the person calling and emailing us in between huge case trials to give us advice. His advice was on point. We had other attorneys shy away from the big bank employee name but Jonathon rose ...to the challenge to do what was right based on principle and ethics. He is sharp and efficient and gets it done without quitting or taking the easy road. When we were in a critical and emotional place, he helped move us toward stability and hope. If you want someone who will stand firm and fight for you, Jonathan Sack is the person you want on your side. We are deeply grateful.

Best in class

Jonathan was great - he helped answer all of my questions about my severance package and offer letter from another firm. He was very responsive and gave me lots of time and attention. I highly recommend him to anyone.

Insightful Advice, and Very Prompt

I asked Jonathan to review my employment agreement. I sent it to him on a Sunday, and he gave an answer in 30 minutes. In our follow up discussion at 9 PM (!) two days later, Jonathan was very thorough. He pointed out a number of flaws in the agreement. Ultimately, he put my mind at ease on the matte...r. It is evident that Jonathan has many years of experience and great insights. I would definitely engage him again and I would highly recommend him to everyone. Bottom line: Jonathan has great experience and knowledge and works 24/7 for clients - what can be better than that!

Excellent counsel

Jonathan is excellent. He is incredibly knowledgeable, experienced, responsive, and tenacious. He is the only counsel I would consider recommending for employment related matters.
