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.

Provided a boost to my confidence at a trying time in my career
Jonathan was recommended to me in the midst of a crisis in my career and provided me with the confident coaching I needed to effectively negotiate a generous exit package with my employer.

Gave valuable advice on negotiating, which in the end came to a resolution for which he did not need to get involved directly and for which he only charged a small fee to review the agreements. Yes, he can be very to...

Successful outcome, professional, efficient
My employer did not honor a contract. Jonathan helped me to get the money that I deserved. He and his team bring intensity and get the job done. I recommend Jonathan to those that wish to pursue a FINRA suit.
"Jonathan is one of the most professional, effective, and direct attorneys I have ever met. His knowledge of labor and employment law is vast and very respected. You can't go wrong having him on your team."
