Perhaps uniquely the firm operates free weekly outreach and advice services in multiple locations across South London, Surrey and West Kent through its own dedicated unit called DVLAAN (Domestic Violence Legal Advice and Assistance Network), which deals with the multiple issues relating to Domestic Violence.
Helen was a non-executive director of the Croydon NHS Primary Care Trust from January 2005 until retiring in March 2007 to concentrate on becoming an MP. Her role at the Trust involved supervising and overseeing the delivery of integrated healthcare for the community, holding to account the professionally lead executive and helping to ensure best use of financial resources to maximise benefits for patients.
