    Client testimonials

    “Karen provided us with an excellent service in (a number of) cases. One case in particular involved two litigants in person and considerable documentation. The clients were extremely pleased with her handling of what was a sensitive case for them and of the successful result. Her manner with clients was good and put them at their ease. She has also performed well on cases where there was a need for greater intellectual input and skilful advocacy. Her reporting back is excellent. She is backed up by clerking at 3PB which is first class.”

    “Karen was outstanding over the two days and secured the very best possible outcome for us.”

    “I would also just like to say a massive thank you to you and to congratulate you on the excellent result yesterday, which I put entirely down to you. I am so impressed and I must say you have been a pleasure to work with throughout. I will 100% try and book you for any upcoming hearings I have in the future and cannot recommend you highly enough.”

    “your understanding of these matters and the manner in which you conveyed it to what appeared to be the most strict judge ever, was great. Furthermore, your cross examination of the cohort of (claimants) certainly taught them a lesson and was a pretty merry occasion for the three judges who could not contain themselves sometimes at the answers being received as well as the manner in which you had shown these (claimants) to be lying about various if not all statements they had made earlier. You had clearly shown (the first claimant) potentially what would happen to her when her case started and she was very fearful of your attendance at her hearing.  Even more so, you obtained a costs hearing and costs against the claimants… Once again our heartfelt thanks and gratitude for your assistance.”

    "Karen's strategy, foresight in the approach and cross-examination seemed to me to be truly exceptional. I never for one moment expected that the Respondent would seek to settle part way through the hearing, and I am convinced their surprising haste to settle part-way through the hearing was completely due to Karen."
