What we do.

At Cosmich Simmons & Brown, we practice more than law. Loyalty, integrity and professionalism are all trademarks of our commitment to each and every one of our clients. That’s why we systematically analyze every legal and factual issue of every case — so we can purposefully develop comprehensive strategies to achieve the most favorable result. With ample staff and resources dedicated to every matter at hand, we protect our clients’ interests efficiently and effectively, always responding to their needs with personalized attention.

Why we do it well.

We have the experience and resources to pursue far-reaching cases with multiple claimants and across jurisdictional boundaries, taking a creative and innovative approach in each one. Maintaining a comprehensive database of medical literature, expert witnesses, discovery materials and more, our experienced paralegal and support staff manages all manner of cases with large volumes of documents and extensive discovery. Along with state-of-the-art document imaging and management systems, we utilize sophisticated trial presentation software to develop audio-visual presentations of technical, scientific, financial or other information to present each and every case with supreme clarity.

In short, we prepare each and every case as if it were going to trial — because we believe that the best results can only be obtained when the opposing party believes we will aggressively try a case if our client chooses not to settle.
