Helping His First Client

Sergio's very first client after starting his own law firm was a single mother who had been taken advantage of by her previous attorney in a divorce action. In fact, that attorney had sued his client and had been given an arbitration award in excess of $50,000. Sergio filed a trial de novo (an action to challenge the arbitration award) and took the case all the way to trial, where he was able to obtain a judgment against her former attorney. Not only was the $50,000 arbitration award wiped out, but Sergio's client was also awarded the attorney fees she incurred in the action. It was a complete victory.

From that point forward, Sergio knew two things:

  • One, that he only wanted to help those who didn't have a voice in our legal system, and
  • Two, that superior preparation over adversaries almost always produced victory and success for his clients.

Not surprisingly, this became the story of his career.

Sergio continues to use this time-proven philosophy in his every day law practice. He has represented both juveniles and adults in criminal law matters, and whether his client’s matter is relatively small or involves life or death risks, he applies these same principles to achieve victory for his clients.

The approach Sergio and the law firm takes to cases is simple: we employ a unique, proven strategy that puts our clients, as well as their backgrounds and personal circumstances, front and center. We do not use cookie-cutter defenses, as each client and each case is different. Much of our success has been the result of our ability to recognize this uniqueness and use it to attack the prosecution's case.
