Janine Collier

Executive Partner, Medical Negligence

Janine Collier, partner, medical negligence specialist & cerebral palsy claims solicitor in Cambridge

I am the Head of the award-winning and Top Tier Legal 500 Medical Negligence Team at Tees. I have been doing medical negligence work now for over two decades and have recovered £millions in compensation for victims of medical accidents.  

How can I help you?

I work with our dedicated team of specialist lawyers and experts to help you understand what happened; to help you access the best possible treatment and rehabilitation; to secure maximum compensation; and to help you to positively plan for the future.

I have extensive experience in all kinds of medical negligence cases, but more recently I have sub-specialised in cases involving: 

  • Child birth injury, e.g. cerebral palsy, learning (neuro-cognitive) difficulties associated with extreme prematurity
  • Maternal birth injury such as incontinence after childbirth due to damage to the anal sphincter complex.
  • Adult brain injuries, particularly cases involving delays in diagnosing a brain tumour and strokes
  • Delayed diagnosis of sepsis
  • Amputation
  • Sight loss - I have received Visual Awareness Training from Support4Sight to enable me to best work to support those with sight loss. 

My expertise, coupled with access to a network of leading medical professionals, enables me swiftly identify the case issues, to give straightforward realistic advice at the outset and to achieve the best possible outcomes for you.  

Going above and beyond anticipating the need for assistance and support throughout the litigation progress,  I work with my colleagues to ensure that you receive access to financial advice and support, case management and rehabilitation services.

What else should you know?

I love my work!  Being a medical negligence lawyer is more than a job – it’s a calling, driving me to make a positive and tangible difference in people’s lives.  Every case is a chance to make a meaningful impact – I am a voice for the vulnerable, I help clients to navigate complex legal and medical landscapes, I seek redress for individuals and I have the opportunity to drive positive change within the healthcare system. 

I graduated from Magdalene College, Cambridge University and qualified as a solicitor in 2001 in a London firm, before moving to East Anglia.  I joined Tees in 2006.

Away from the office, I enjoy spending time with my husband and dogs (a Romanian rescue doggie (Boo), and a Cavachon x Jack Russel, Winnie).  My two children are now at University.  Throughout my life, I have always been involved in sports -  gymnastics, tennis, netball, obstacle races, running a few marathons or Korfball.  

In 2023, I walked Hadrian’s Wall (with a broken toe!) and completed the National Three Peaks Challenge to raise money for the Tees Better Future Fund.

I am a Trustee of Support4Sight and of the charity, Action Against Medical Accidents

Janine's testimonials

Legal 500 UK 2023

'Janine Collier has an amazing reputation and quite rightly, she very quickly spotted something that wasn’t the main focus of the case but is able to zoom out and look at everything that’s going on and spot things others wouldn’t spot. You can tell she really cares and is a very dedicated person who just wants to help. The team are all caring and efficient'



'A heartfelt thank you for all you have done in preparation for and during the settlement meeting, as well as for your unfailing support along the way, in and out of hours. It is undoubtedly due to your high professionalism if the outcome today has exceeded all expectations; it will be a huge help for us going forward and we will be forever grateful'

'Janine Collier is renowned for her handling of delay in diagnosis, obstetric injury and surgical negligence claims. She is at the top of her game and knows clinical negligence inside and out'

Susan Hickman


'We consider ourselves fortunate to have been recommended to Tees by the solicitor we initially approached. We did not realise it until the case was well established that the level of professional care we were receiving was exceptional and that the experience of the individuals and the contacts they have to assist in a very complex case was the best available.
We are grateful that we received a satisfactory settlement as a result of their efforts under difficult circumstances and dealing with defendants that were obstructive and disorganised. By far the greatest benefit for us however is the fact that the victim, with assistance from highly skilled experts that we would not have known about otherwise, learned to walk short distances when all other medical opinion did not consider this possible. This was their greatest achievement which is well beyond the service we expected'
