Meet Jonathan M. Rosenthal (JR)


I have been practicing criminal law as a sole practitioner for more than 25 years. I have also been teaching trial advocacy to both lawyers and law students for almost 15 years. There are challenges facing our profession. My experiences as a litigator, teacher and sole practitioner give me the perspective and connection to all members of the bar, from recent calls to multi-decade practitioners, to serve you as a bencher.
