Expert Role
The Role of a Pain Management Expert Witness
Pain management expert witnesses serve a defined function in litigation: they translate complex medical evidence into opinions that meet the evidentiary standards required for admissibility and persuasive weight in court. In personal injury and medical malpractice matters, pain management is a frequent point of dispute — both because the specialty spans a wide range of conditions and interventions, and because chronic pain is difficult to objectify without clinical training. For the clinical methodology underlying an objective pain management evaluation, see the article on how pain management experts objectively evaluate pain.
Dr. Dardashti provides opinions on diagnosis, causation, standard of care, prognosis, and the appropriateness of treatment. His role as expert witness is distinct from that of a treating physician: he is retained to provide an independent, evidence-based analysis of the medical issues in the case, not to advocate for either side.
Dr. Dardashti is available for deposition testimony, arbitration proceedings, and trial testimony nationwide. He is experienced with both direct examination and cross-examination in complex pain management cases, including matters involving CRPS, spinal cord injuries, and disputes over long-term treatment necessity. Attorneys who retain Dr. Dardashti for testimony receive a written expert report, a curriculum vitae, a prior testimony list, and, where applicable, a fee schedule.
Contact Expert Medical Services LLC with a brief description of the case, the type of engagement needed, and the applicable deadlines. For matters venued in California, Arizona, Florida, Nevada, or Texas, see the dedicated state pages below for jurisdiction-specific information.

FAQ
Common Attorney Questions

- Dr. Dardashti is board certified by the American Board of Anesthesiology with subspecialty certification in Pain Medicine. His opinions are grounded in peer-reviewed medical literature, clinical practice guidelines, and active clinical experience in pain management.
