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. Cass has direct experience with first and third party property matters, bodily injury, personal injury, construction defect, errors and omissions, directors and officers, catastrophe, contract actions and everything in between. 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 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.

Rates Information

Zoom Mediations: Rates are $400 per hour with a 2-hour minimum ($800) and are limited to 4 ½ hours. An all-day mediation can be reserved with a 4-hour minimum ($1,600), and no limit on the number of hours. Multi-day mediations (at 11 hours per day) can be scheduled at $3,000 per day, requiring a 2-day minimum ($6,000), and are both optimal and highly recommended for multiple pre-suit or corporate clients with routine litigation. There are generally no administrative charges. Rescheduling with less than 24 hours’ notice will not incur a cancellation fee if the mediation goes forward as newly rescheduled. Cancellations within 72 hours’ notice, or cancellations of formally rescheduled mediations, incur the minimum charge for the respective mediation booking as noted above. All charges for Zoom mediations are split among the parties, unless otherwise agreed in writing. Rates for in-person mediation remain the same, though there is a 3-hour minimum for half-day ($1,200) and 6-hour minimum for all day ($2,400) in addition to travel (mileage/airfare/parking/toll), lodging (hotel if overnight travel for early morning or all-day mediation is necessary), and mediation space (if one of the parties cannot accommodate meeting space).
