Criminal Defense

Criminal defense is more than a practice area, it is a passion for Attorney Warren.   

Attorney Warren represents clients at all stages of a criminal case, from arraignment to trial or disposition.  

Throughout Massachusetts

Although his office is located in downtown Boston, Attorney Warren represents clients in courts throughout Massachusetts, including Suffolk, Middlesex, Bristol, Norfolk, Plymouth, and Worcester counties.

Superior, District, Boston Municipal,

and Appellate Courts

Attorney Warren represents clients facing serious charges in the Superior Courts, such as armed robberies, armed assault to murder, rape, and drug trafficking, to less serious charges such as drunk driving (operating under the influence) and disorderly conduct.

Attorney Warren also handles appellate cases in the Supreme Judicial Court and Appeals Court.

While the strategies might change, the approach remains the same:  every case matters; every client matters.

Trial lawyer

Webster definition:  a lawyer who engages chiefly in the trial of cases before courts of original jurisdiction.
