Karen joins from Shoosmiths, having also previously worked at Howard Kennedy and Dechert.

She also has considerable expertise advising on the people-related aspects of corporate transactions, and regularly acts as lead employment counsel on mergers, acquisitions and investments.

Karen becomes the sixth member of the firm’s Employment team, which is led by Tania Goodman along with Partner, Andrew Granger. The Employment team sits within the firm’s Commercial Services department alongside the Corporate and Commercial teams.

Commenting on Karen’s appointment, Tania Goodman, Head of Employment at Collyer Bristow, said:

The team is highly regarded for its practical and commercially focused approach, delivering clear, solutions-driven advice to a wide range of clients.
