The firm has a strong reputation for its conduct of serious and complex crime and is regularly involved in high-profile cases.

The firm has a dedicated team of solicitors for the more serious Crown Court cases and its in-house higher courts advocates ensure continuity of representation for clients from the police station to the conclusion of their Crown Court trial.
