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.

Incredibly User Friendly

Jonathan is truly one of the best. When I reached out to him for advice not only did he take the call quickly, but he did also so in a way that was thoughtful and comprehensive. He helped my partner and me think through the specifics of the situation and laid out what he believed to be the best pat...h forward. He's extremely knowledgeable and fair and isn't going to sign up for something where he doesn't think he can bring value. I appreciate that about him and while I hope we never need him again, if an issue were to arise, he is our first call and if I were you, I'm make him my first call.

Knowledgeable and Responsive

A contact and previous client referred me to Jonathan Sack. I had a complex separation agreement. Jonathan reviewed the agreement in detail, advised me on my options, and took the time to walk me through everything and answered all my questions. Prior to connecting with Jonathan, the ambiguity and co...mplexity was overwhelming. After speaking with Jonathan, I was confident that I fully understood the agreement I was entering into and left nothing on the table. I would highly recommend hiring Jonathan for any of your employment and labor needs.

Professional and genuine

I sought Jonathan's representation when my employer let me go after years of discrimination. He was professional, persistent, and genuinely cared about my situation. He quickly negotiated a severance package more than four times what was initially offered to me. I would certainly recommend him.
