About Roger D. Klein
Roger D. Klein MD entered the legal profession after completing a law degree at Yale Law School, where he earned his J.D. in 1996. He carries the MD designation in his name, a marker of medical training that shapes how he thinks about legal problems. His background places clinical judgment and legal analysis in close conversation.
Klein's path blends two disciplines that rarely travel together. Trained as a physician and as an attorney, he has approached cases and advisory work with attention to both clinical realities and statutory demands. That dual perspective informs how he evaluates evidence, assesses risk, and frames arguments. Colleagues say he brings a methodical eye to complex factual records and an ability to translate clinical issues into legal terms.
Early in his career he moved between roles that demanded both legal rigor and medical insight. He has worked on matters that required understanding medical records, standards of care, and regulatory frameworks. In litigation settings he has responded to technical expert testimony. In advisory roles he has helped clients interpret rules and policies that affect clinical practice and research. He has also been involved in projects that required careful document review and coordination among multidisciplinary teams.
Klein has maintained ties to both the medical and legal communities. His training allows him to speak the languages of clinicians, hospital administrators, regulators and lawyers. That fluency is often useful when negotiating settlements, preparing regulatory submissions, or developing compliance programs. He aims to present complex medical detail in a clear, neutral way so decision makers can evaluate the legal issues at hand.
In professional settings he has been active in memberships that relate to his fields of practice. He has worked with peers to stay current on evolving standards and to discuss practical solutions to emerging problems. Over time his practice has moved in step with shifts in healthcare delivery, regulation, and research governance.
As of 2026 Klein maintains an active law practice that draws on both his medical and legal training. He advises and represents clients on matters where healthcare, clinical practice and law intersect, concentrating on regulatory, compliance and litigation issues tied to health care and clinical research.
