Who is Casimir (Cass) Maliszewski?

Over the last 26 years, Cass Maliszewski has been in the courtroom for trials more than 100 times in both the chairs of the defendant and the plaintiff.  More importantly, he has personally participated in and negotiated thousands of mediations and has been responsible for thousands more in leadership positions within the Property and Casualty insurance sector.  Cass has been integrally involved in cases from eight figures to those with non-monetary issues as the sole driver.  He is a member of the Claims and Litigation Management Alliance, holding its prestigious Claims Litigation Management Professional certification obtained through its Litigation Management Institute as held at Columbia Law School, and speaks at conferences both locally and nationally on the subjects of leadership, litigation management, negotiations, and alternative dispute resolution.

Before retiring, Cass worked at several insurance carriers managing and handing claims, coverage and ECL disputes and providing strategic advice and direction to claims and litigation organizations.  In his final corporate role as the Director of Litigation and Casualty Claims for the second largest property insurer in Florida, Cass oversaw internal and external teams conducting litigation work; partnered with law firms in the delivery of legal services up to and through trial and appeal at a claims level and extracontractual level, as well as regulatory matters, when called upon.  Cass was responsible for annual $85mil indemnity/$20mil expense and litigation and casualty staffing and oversaw reinsurance audits and reporting for the company’s litigation.  He also provided strategic guidance for the claims division with respect to potential litigation.

Cass has experience in State and Federal Courts primarily in Florida, but also experience throughout the entire Southeast, Pennsylvania, Virginia, Colorado, and Arizona over the last two decades.
