About me

I have been practicing criminal law at Wallin & Klarich since 1995 and have handled all types of matters. I represent clients in all Southern California Counties. I have had success against government prosecutors at the County, State and Federal level, whether be at the investigation/negotiation, trial or sentencing stage. I pride myself in providing each and every one of my clients with judicious legal representation as well as apt communication about their cases
