Jonathan helped me settle with my previous employer. He was fast, direct and efficient. From what I saw his experience in my field of work allowed him to settle my case as smoothly as possible. His compensation structure was also something that helped me to go into the negotiation process. I have al...ready recommended him to my friends who are seeking legal advice and will continue to do so.

Jonathan advised me through the negotiation of a structurally complicated situation. 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... the point and sometimes hard to reach ... but able to read a situation very well, is efficient and honorable.

Sack is a big talker but ultimately doesn't deliver. He took a case on contingency then let it languish for over a year with no progress. When I pushed to move it forward he demanded a retainer as a condition completely disregarding the original agreement. Though his website states he handles matters... personally he not only handed off my matter to a very rude and ineffective associate but insisted I draft a significant portion of the complaint that he never filed. I have no confidence in this man
