IMS Certified Life Care Planners develop comprehensive, peer-reviewed life care plans grounded in medical evidence, projecting the future medical care a catastrophic personal injury may require. Our vocational experts assess the injury's impact on a person's ability to work, quantifying lost earning capacity and the long-term effect on employment. IMS economists then calculate damages to ensure long‑term financial losses are measured accurately and supported by accepted economic principles.
