I am a results-oriented, energetic advocate for my clients. I am passionate about representing my clients. As most cases come from word-of-mouth referrals, I am proud of my reputation built one client at a time. Most clients are faced with a difficult challenge in a critical part of their lives: their jobs and careers. I am competitive and look forward to taking the fight to the employer to redress unfair and illegal actions. I align our firm's fee arrangement with the client's desired outcome so that there is an identity of interest in the result sought. My success is defined by each client obtaining the desired outcome as a consequence of my effective counsel. Most of all, I love what I do, and that is helping people and seeking fair results for clients who deserve better treatment from their employers.

Jonathan is fantastic. I used him when I was wrongfully terminated two years ago and again this year. He is more than a lawyer. He is a confidante and an advisor. He gets results because he is thorough but he is also a great sounding board for smaller issues. He is fearless on behalf of his clients. ...

A contact and previous client referred me to Jonathan Sack. I had a complex separation agreement.

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.
