Daniel Cohen, Attorney At Law, maintains a sole-practitioner criminal defense practice on Grossmont Boulevard in La Mesa's Grossmont area, representing clients in DUI/DWI, drug, domestic violence, and sex-crime cases across San Diego County. DUI defense includes Administrative Per Se Hearing representation before the California DMV to challenge license suspensions, working alongside the collision-repair documentation from shops like John's Automotive Care when vehicle evidence is relevant to BAC-timeline reconstruction. The practice handles California Penal Code Section 1203.4 expungement petitions that allow qualifying defendants to withdraw guilty pleas and have cases dismissed post-probation. Court-ordered psychiatric evaluation and treatment compliance is coordinated through behavioral-health providers like Alvarado Parkway Institute, whose inpatient and outpatient programs satisfy judicial mandates for substance-abuse and mental-health conditions. The practice's most complex trial work involves multi-count felony DUI cases with great-bodily-injury enhancements under California Vehicle Code Section 23153, requiring accident-reconstruction experts, blood-draw chain-of-custody challenges, and Title 17 calibration audits on Draeger Alcotest instruments.
