The Hammer Law Firm places an emphasis on complex criminal charges, including federal criminal charges, white collar crimes, violent crimes, felony drug charges, gang-related crimes, weapons offenses and sex crimes. We also offer experienced representation on behalf of clients charged with a DUI/DWI, theft, domestic violence or drug possession charges. For a complete listing of services provided, please see our "Products/Services" tab. At our firm, we are innovative and results-oriented. We do not limit ourselves to one single approach or one single philosophy. When a case requires aggressive action, we are aggressive. When a case requires negotiation, we work to negotiate a beneficial outcome. Through decisive and strategic action, we strive to achieve the best possible results that protect our client's rights, record and freedom. Prior to becoming a criminal defense lawyer, Mark A. Hammer, spent more than 13 years as a prosecutor, and taught trial advocacy and criminal procedure to police and prosecutors from Seattle to South Carolina. Mr. Hammer's experience as a prosecutor provides each client we serve with a decided advantage when it comes to presenting a criminal defense in state or federal courts. Knowing how law enforcement officers and prosecutors assemble their case and understanding their motivations can be vital if it is necessary to negotiate a plea or push for a full jury trial.
