Frequently Asked Questions

Please contact us for an initial consultation so we can learn about the details and timeline of your case, discuss with you which expert(s) is best suited for your needs, and answer your initial questions. We are never retained by parties to litigation (evaluees). Please ask your attorney to contact us!

Following the initial phone consultation, we would be happy to provide our rate sheet, retention agreement and a preliminary budget estimate based on records size. Our expert(s) are fully retained and will start working upon receipt of the executed retention agreement and the initial retainer payment.

Yes! We have experience with the complex dynamics, logistics and ethical issues of multi-plaintiff litigation. Our experts can provide evidence-based opinions regardless of the number of plaintiffs. Our paralegal team is trained to handle large volume of records, and can create medical chronologies, summaries and other work that speeds up the review of our experts. Previous experience with mass tort litigation includes survivors of workplace shooting, train collision and bus accidents, PCB contaminated water table, mold exposures, housing discrimination (for the Civil Rights Division of USDOJ), sexual abuse claims, public utility gas pipeline explosion, massive fires etc.

Typically, the psychologist reviews any psychological records, administers psychological test to the evaluee, and provides a summary of test results and findings to the psychiatrist. The psychiatrist, as the lead expert, reviews the majority of medical records (except psychological records), depositions, and other relevant documents and data. He or she then performs a multi-hour Independent Medical Evaluation (IME)  and prepares a detailed report of findings in an evidence-based opinion informed in part by the findings of the psychologist. There is no duplication between the psychologist and the psychiatrist, only complementarity. Not every case requires psychological testing. Please contact us to discuss the specifics of your case.
