About Ash

Ash is qualified in both New York and the UK, specialising in Data Protection and Privacy, Blockchain, Digital Commerce and Technology.

Her time working in-house as Global General Counsel for a multinational financial services organization with over USD450billion assets under management, and as external General Counsel for a start-up, have given her unique insights into the operational requirements and risk appetites of different industries and businesses. She listens to her clients, and identifies the  optimum strategy to meet their needs and priorities.  Whether advising on data privacy, technology or digital commerce, Ash’s advice is pragmatic and solutions focussed.

Her privacy practice often involves an international flavour as she can advise on the laws from both regions, leveraging jurisdictional comparisons and similarities to generate sensible solutions. Where possible, she leverages existing compliance frameworks.
