Jen Shipley | Director in Medical Negligence | Fieldfisher
"From my point of view, I have had a very positive experience from the service provided by yourself of McCollum Consultants and Dr Gorton. The initial contact was quick and easy having been referred by NCA and service was professional and informative with relevant guidance on what assistance could be provided. This was then followed up with terms of business, timescales and a product provided, as requested, and promised. In my opinion as a Senior Investigator, utilising McCollum Consultants and you has been very easy to secure an expert witness. It has also been invaluable to have yourself overseeing the process, giving guidance, identifying the expert witness, liaising with the expert witness, collating information, and ensuring the final report was available."
