Four colleagues have been promoted to senior associate, recognising their leadership and specialist knowledge:

• Kate McCue, team leader, clinical negligence

• Lucy Atherton, team leader, education, community & residential (ECR)

• Nathalie Swanwick, team leader, abuse

• Sean Harrison, solicitor, child care proceedings

The associate promotions include:

• Joshua Hurst, abuse team

• Sarah Warburton, child care proceedings

• Sinead Jest, child care proceedings

In addition, Lidia Foster has returned from maternity leave to resume her role as partner in the child care team, following her promotion in 2024.

Commenting on the announcement, CEO Greg Cox said, “We’re fortunate to have an incredibly talented team, and this year’s promotions reflect the outstanding contribution these individuals make to Simpson Millar’s culture, performance and client service. Their drive, integrity and commitment to their clients and colleagues are at the heart of what we do. I’m delighted to congratulate them on this well-earned recognition.”

These promotions span offices across Simpson Millar’s national network and underline the firm’s position as a leading employer in the legal sector. Recognised by The Legal 500 and Chambers, the firm continues to grow and is currently recruiting into its personal injury and public law practices to meet rising demand.
