For John the devil is in the details. Known for being meticulous and analytical, his clients benefit from his methodical approach to litigation.

An experienced and skilled trial attorney, John has tried cases in both state and federal court, including several federal jury trials. He represents both private businesses and governmental agencies at trial, mostly defending against claims of employment discrimination and civil rights violations. In addition to trying cases, John has extensive experience in all facets of litigation, from initial intake and discovery through summary judgment. John understands that the proper handling of a case from filing through dismissal or trial is often an arduous and nerve-wracking process for a business. To that end, he works with his clients on their cases from beginning to end, whether that be through trial, summary judgment, or settlement. John understands that in litigation, one size does not fit all, and that the specific facts and needs of his clients will dictate the direction of litigation

Though John is a skilled litigator, he also counsels clients on liability issues well before they reach a court room. He represents employers and business owners in general employment matters, including discrimination claims, and wage and hour issues. 

Having studied biology prior to law school, John has a habit of diving into new discoveries and a passion for learning. This serves his clients well as he comes to understand their industries and the details of their businesses. John entered the legal field knowing his work would impact people. He never fails to consider how each decision and outcome will impact his clients.

John doesn’t shy away from a challenge either. He once had a breach of contract case with a single plaintiff against a large corporation. Going up against a much bigger and better financed firm, John was able to secure a verdict for his client. This taught John the value of perseverance and to never quit the fight, no matter how daunting the odds may seem.
