“great courtroom advocate and cross-examiner”

The Legal 500 2023

“Just to let you know the client wanted me to extend their thanks to you and said you were “unanimously thought of by the [Trust]’s attendees as highly professional, knowledgeable and persuasive but yet humane and down to earth.”


“Great compliments from the client…so much so that they have asked if it would be possible for her to do [another] case for them…Their comments included how good she was at cross-examination, but still treated the Claimant with respect.  Good barrister, with a human side.”


“Just to let you know I was very impressed with Tara today and have just heard from client, as I left early, to say that she was brutal in cross-examination.”


“Please pass on my thanks to Tara, an incredible barrister who was so calm but firm and very professional… almost immediately she put us at ease and said think of it as an experience and what an interesting experience it was. I knew as soon as I met her I would be in good hands. Of course I’m over the moon and grateful with the outcome but even if I didn’t win I would still be sending this email because I could see the dedication and drive…Great team work all round so many thanks to all involved.”


“I would be grateful if you could pass on a note to Tara’s head of chambers.  I would like to thank her and particularly make note to her chambers how effective and professional she was…Without her we would not have uncovered vital evidence of poor care, and the court may well have retired ignorant of potential further risk to life from the lack of a robust process put in place following a serious medication error leading to the death of my mother. I and my family are hugely grateful to her for the diligent work and the care she took meticulously presenting evidence and questioning the relevant parties. I feel that justice was served that day and I owe much of that to Tara, without whom it may have been impossible to get to the bottom of the case details. She was clearly significantly more professional and better prepared than her opposition, and was a credit to your chambers. You have a young lady to watch, she will go far! Many thanks from a grateful family.”


“I just want to thank you again, it was a pleasure to meet you and get to know you over the last few days. You are a credit to your profession, the perfect choice for us because of your wonderful passion for justice and fairness and I hope that you never lose that, particularly reflecting on the tough world that you’re in.”


“Just a quick note to say thanks for doing such a top rate job today. I can’t overestimate the attention it received from [the] senior management team… It’s been a while since I observed a FT trial, still I thoroughly enjoyed watching you batter the Claimant’s poorly prepared and woefully presented case into oblivion! Will – Tara was excellent today!”
