Medical Malpractice Expert Witnesses: 88

Spine Surgery and Spine Medicine Consultant

The concepts of evidence-based medicine have been the cornerstone of Dr. Dillin’s education during his spine surgery fellowship in Neurosurgery and Orthopaedic Surgery and the format for decision-making in his subsequent practice. The critical analytic features inherent in the ‘best evidence’ approach to patients have permeated his writing and his lectures, allowing flexible adaptation as the science has changed. Since July 1985, Dr. Dillin has been exclusively devoted to clinical spine, interventional spine, and spine surgery practice. The combination of clinical critical thinking in conjunction with evidence-based medicine practice, allows spine specialty focus on any Independent Medical Evaluations or Medical-Legal Reviews. He is in clinical practice performing spine surgery, spine interventions, and evaluating patients with spine conditions. He is licensed in California, Texas, Arizona, Florida and Nevada. Dr. Dillin was a former partner at the Kerlan-Jobe Orthopaedic Clinic. I spent 2022-2023 in clinical practice and at the Effective Writing in Health Care program sponsored by Harvard Medical School. The program encompassed online and onsite (Boston) attendance. My study subject was the history of the expert witness in general, and more specifically, the medical expert witness. My capstone project, from the ‘Writing for the Public’, division is attached. This is the narrative account of “The Trial of the Medical Expert Witness.”

Litigation Support - For over 35 years, Dr. Dillin has traveled to refine and acquire the technical skills invested in Spine Surgery and Spine Interventions. His expert witness activity is embodied in his Harvard Capstone, "The Trial of the Medical Expert Witness." Dr. Dillin offers Independent Medical Evaluations and/or Medical-Legal Review, thorough reporting, depositions, and trial testimony as needed.
