Why hire Mark

 When you hire Mark J. Andersen, you actually get Mark J. Andersen. “I make myself available and I keep my clients informed at every stage of the process”. 


Many people who start their criminal case represented by a public defender end up retaining Mark. “The main complaint I hear from my clients formerly represented by a public defender is that they believed they were getting far too little attention from their public defender. They were not being kept advised. They didn’t know what was going on in their case and they didn’t think that the public defender was fighting for them. I worked with many public defenders while I was a prosecutor and I remain friends with several today. Most public defenders are competent, knowledgeable, hardworking and talented. The problem is that they are overwhelmed by truly unmanageable caseloads so their ability to give particularized attention to each case can be severely limited.”

As a private criminal defense attorney, Mark consciously maintains his case load at a manageable level benefiting his clients with the attention they deserve and providing a well prepared defense. He says, “I care greatly about the people I represent and work, in every case, toward achieving a great result.”
