She leads a team of four solicitors and two paralegals.

She has been at the forefront of legal challenges to the Government’s welfare system, Universal Credit, and was named Times Lawyers of the Week in December 2018 for successfully representing six refugee families in their bid to obtain entry to the UK after being stuck on a British military base in Cyprus for 20 years.

In 2011 Tessa was shortlisted for the Peter Duffy Young Human Rights Lawyer of the Year award; in 2013 she was named The Times' Lawyer of the Week; and in 2014 she featured in The Lawyer’s annual Hot 100 list.  

Tessa graduated from the University of Manchester with a First Class BA Honours degree in Politics and Philosophy. Following three years working abroad in Japan and Cuba she obtained an MA in the Idea of Toleration at the University of York. She converted to law and completed the PGDL and LPC, both with distinction, before qualifying as a solicitor at Bates, Wells & Braithwaite Solicitors in 2008.
