Former client on TrustPilot
''I’d like to give my sincere appreciation to Wallis Crockford for the way she has supported me and my family throughout our medical negligence claim. Throughout the process Wallis has been proactive, determined, clear in her advice and very empathic to our situation. She has always set realistic expectations and has done exactly what she said she would. I’m so happy that our claim settled successfully, but I will miss my interactions with Wallis!''

''During a stressful time reliving and unpicking the events of my medical negligence case, Wallis was an unfaltering point of contact. She kept me informed every step of the way, managed by expectations, patiently explained things, and made me feel that there was no question ‘too silly’ for me to ask. She has been sensitive, reassuring, and professional, from start to finish. I would 100% recommend.''
