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
