Profile

Sean qualified as a solicitor in 1992 and has practised as a solicitor-advocate specialising in criminal law since that time. Throughout his career his work has included offences across the criminal spectrum. He was one of the founding partners of Needham Poulier and Partners, a firm specialising in criminal and mental health law. Whilst at the firm he started concentrating on Higher Court Advocacy work and ultimately left private practise in 2014 in order to focus solely on higher end crown court advocacy work. Between 2014 and May 2021 a huge proportion of his work were multi-handed trials heard at the Central Criminal Court.


Sean is highly respected by fellow advocates and judges and is valued the for his ability, integrity, and
powerful work ethic.


In May 2021 Sean joined that Crown Prosecution Service as a District Crown Prosecutor in the Crown Court Trials Unit. During his time at the CPS, he was an area lead in disclosure, international work, and forensic work. He was also at the vanguard of how to drive efficiency and excellence within the CPS. He has now brought all of that learning from the prosecution side back into the defence ranks by joining the Public Defender Service
