Meet JR

I have been practicing criminal law as a sole practitioner for almost 30 years. I have also been teaching trial advocacy to both lawyers and law students for 20 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 once again serve you as a bencher.

The Statement of Principles is a very small step in the right direction. In my opinion, the lawyers who oppose this initiative do not understand our profession or our public responsibilities.
