About me

I am a trial lawyer who primarily practices in the Federal courts in Maryland and the District of Columbia as well as the State courts in Prince Georges and Montgomery County, Maryland. I take each client's case personally because I know that this is one of the most difficult experiences in their lives.  I have over 30 years of experience in both Federal and State court and I have handled many complex cases involving Murder, Racketeering, Narcotics as well as Appellate work. I look forward to assisting you  and providing you with the best legal representation possible.
