Sarah Collier

Public Law Associate Solicitor

Sarah Collier is an exceptional person. Her professionalism, in terms of her confidence, dedication and efficiency in preparing my case helped me to know and feel that I was in safe hands. Sarah showed empathy towards me as my situation regarding my health was highly sensitive. I was always kept informed and updated and she always ensured attention to details. I was always given the assurance that I could contact her via email/phone (if needed) when she was on annual leave or she would go out of her way to call me (on weekends) to make sure that I was okay; as the case was extremely difficult and emotionally draining at times with it's twists and turns. Sarah provided the intellectual insight and rationale that enabled me to make sound decisions when moving forward. Eventually, I was able to determine and identify the factors and circumstances that had systematically prevailed to impede the development of my mental health and take appropriate action(s) to rectify the situation. Thank you Sarah for your sincerity. compassion and unwavering commitment to secure justice for me. I admire your strength, tenacity and fortitude in this matter. I would definitely recommend your services.Naamah-Shalomit Shayahlah
