An industry-recognized securities litigator

A true "outside the box" thinker, Jonathan brings a determined and unique approach to his advocacy, leaving no stone unturned in finding the right litigation strategy for his clients. In past cases, his determination has driven him to master Cayman Islands law in order to defeat a derivative claim, and mine public filings to unearth evidence that a seemingly strong securities claim was time-barred — leading to an authoritative Second Circuit decision on the subject.
