How we help you identify the right medical expert witness
Finding the right medical expert witness involves more than matching a case to a clinical specialty. We consider the specific clinical or professional issues requiring independent opinion, alongside relevant qualifications, specialist knowledge, current or recent practice, professional experience, medico-legal expertise and availability.
We can recommend appropriately qualified experts whose experience is relevant to the issues in dispute, helping solicitors and other instructing parties make an informed choice. For complex cases involving multiple areas of medicine or healthcare, we can also help identify and coordinate experts across different clinical disciplines.
