People come to our firm because we are known for our dedication to clients and commitment to legal excellence. We are committed to providing quality legal representation that is focused on obtaining results and delivering personal service.
Our Approach
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.
Our Experience
Prior to becoming a criminal defense lawyer, founding attorney, Mark A. Hammer, spent more than a decade as a prosecutor, and taught trial advocacy and criminal procedure to police and prosecutors from Seattle to South Carolina. We believe strongly that 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 when the time comes to negotiate a plea or push for a full jury trial.
