Niall joined us in 2013, part way through his training period, and qualified as a solicitor in May 2014. Niall has worked as a specialist Clinical Negligence Solicitor since qualifying and now supervises and assists other members of the Clinical Negligence team. Niall has also been admitted as a Solicitor of the Court of Judicature of Northern Ireland.

Prior to completing his law degree in July 2010, he obtained a BA (Hons) in Accounting and Finance. Between finishing his studies and joining Price Slater Gawne, he has worked as a Costs Negotiator at a North West based law costs firm. Niall also gained valuable experience working closely with senior Solicitors and Partners on high value brain injury and clinical negligence claims at a niche Merseyside Personal Injury firm.

Outside work Niall is a keen golfer and sails when time allows.
