Medical Negligence

Madeline Seibert

Technical Director - Medical Negligence

I'm passionate about uncovering the truth and fighting for justice for those who've suffered catastrophic injuries through clinical malpractice.

Expert profile

Get to know Madeline

I have over 20 years' experience as a specialist medical negligence solicitor. I joined Slater and Gordon as the medical negligence technical director in 2019 following my role as partner and head of medical negligence at a regional legal practice. I was delighted to be given the opportunity to use my skills and experience at a national level at Slater and Gordon.

Having more than two decades of experience, I'm extremely experienced in representing clients who've suffered serious and catastrophic injuries as a result of medical negligence. I have a specific specialism in representing children with brain injuries caused by birth injuries.

Career highlights

In the two decades I've been specialising in medical negligence, I’ve had many career highlights. I see it as a privilege to help to secure justice and much needed compensation to aid rehabilitation, housing, care and support. I'm very proud to have helped so many deserving people to move forward with their lives after suffering from catastrophic injury.

Most recent highlights include a cerebral palsy case settlement of £14.4 million and a Court of Appeal case where treatment of meningitis was delayed in a 13-month old baby in which compensation was secured for the child in the sum of £4 million.

Recently, I supported a client, Charlotte who had received delayed treatment for their vitamin B12 deficiency. The delay in treatment resulted in irreversible damage to her spine and optic nerves, which has left Charlotte having difficulty walking, due to hypersensitivity, serve numbness and pain in their back and impaired vision. Even though Charlotte is now receiving the treatment needed to manage their vitamin B12 deficiency, the damage caused to Charlotte will stay with her. The compensation that was secured for Charlotte's claim has helped Charlotte get her independence back.

You can find out more about Charlotte's case here.


I have a number of accreditations. I’m an accredited panel member for both the Law Society for Clinical Negligence and AvMA (Action Against Medical Accidents). I'm also an accredited Senior Litigator by APIL (Association of Personal Injury Lawyers) and Clinical Negligence Panel Member for APIL. I'm also an accredited APIL Assessor for Clinical Negligence panel applications.

Additionally, for the past several years I've been recognised and recommended by independent legal guides, the Legal 500 and Chambers and Partners.

I have been included in the Chambers and Partners ranking for 13 years, with the most recent edition ranking me as a Band 3 lawyer and states: "She is a very safe pair of hands and is very loved by clients."

The Legal 500 2023 edition has recommended me as a ‘Recommended Lawyer’ and states: "Madeline Seibert has a wealth of experience in clinical negligence; she is hard working and had great judgment."

I was also a finalist for the Clinical Negligence Lawyer of the Year award at the Personal Injury Awards 2021.

The extra mile

I'm a keen supporter of charities who provide access to justice including Citizens Advice where I was a Trustee for over a decade and AvMA (Action Against Medical Accidents), where I was a volunteer for many years during my early years of practice and more recently have raised funds through running the London Vitality Big Half marathon.
