Personal Injury / Milton Keynes and Luton
I am a Director of Clinical Negligence and Personal Injury at Duncan Lewis. I supervise a team of solicitors, trainees and paralegals who are all dedicated to obtaining the best possible outcome for our clients. In addition, I am responsible for risk assessing all of the clinical negligence and personal injury claims handled by the firm.

I am highly experienced in dealing with severe and complex clinical negligence and personal injury cases including, but not limited to; claims involving birth injuries, brain injuries, surgical injuries and orthopaedic injuries resulting from delay, misdiagnosis or negligent spinal or gastrointestinal surgery. I also have extensive experience in representing clients in ophthalmic cases including retinal detachment and laser surgery claims.

One of my more recent cases involved obtaining a six figure award of compensation on behalf of a client against two NHS Trusts in a complex case following an appendectomy. I also obtained substantial damages against a national firm of opticians on behalf of a client who permanently lost all sight in one eye as a result of the optician’s failure to recognise that the client was suffering from a retinal detachment.

I am a Recommended Individual in the 2019 edition of The Legal 500 for both my personal injury work and my clinical negligence work.

  • ""The service I received over the past three years has been exemplary. In particular, I wish to thank Rebecca Thomas who has worked tirelessly, diligently and efficiently, explaining the legal process in a friendly and professional way. All the legal terminology was explained to me at the beginning of the claim, through to the successful completion. I was kept updated and informed every step of the way by Rebecca. Due to her expertise, eye for detail and dogged determination, the case was successfully concluded. I have finally received the justice I deserved by way of financial compensation. I would certainly recommend your firm “Duncan Lewis” in the event of any medical negligence claim." - Client, Mrs K, 2020

  • "I completely lost my vision in my right eye due to negligence. Rebecca was my solicitor and she has been absolutely great. The case was tricky, with a lot of experts involved including doctors and accountants. The case ended a few weeks ago and I got a six figure settlement thanks to Rebecca who has been proactive in this case from beginning to end." - Maria, 2016
