DeCaro Doran Joins Themis Advocates Group:  With a focus on continued expansion and increased services to our clients, DeCaro Doran Siciliano Gallagher & DeBlasis has joined other law firms across the United States in the Themis Advocates Group and in launching the website for the Themis Advocates Group. 

The Themis Advocates Group is a national network of small to mid-size law firms with a primary focus on insurance defense litigation whose members are similar in their mission and in their openness to exploring innovative ways to better serve their clients in the insurance industry. This national network of preeminent law firms covers a majority of the jurisdictions in the country, with the goal of eventually covering all of the fifty states. After a detailed vetting process, DeCaro Doran Siciliano Gallagher & DeBlasis was selected as a Themis member for defense litigation in Maryland, Washington, D.C., and northern Virginia. Themis’ members share information, expert witness recommendations, procedures, technology, and client feedback, thereby enabling them to provide the most skilled, aggressive, and cost-efficient legal services to their clients. Unlike other defense organizations, the member firms of Themis focus almost entirely on defense litigation, with specialties in virtually all aspects of insurance defense. One of the cornerstones of the organization is the active participation of member firm clients in the many Themis events designed to support meaningful communication between the law firms and clients. 

Since 1993, DeCaro Doran has counted insurance companies, self-insureds and third party administrators among the many clients for whom the firm delivers cost-effective and exceptional legal counsel. DeCaro Doran’s membership in the Themis Advocates Group is yet another tool certain to provide us with the acumen to better serve our insurance clients.
