How we make a difference We commissioned Dr Sarah Senker from ATD Research and Consultancy to report on the impact of our services. Her paper, 'Evaluating and Evidencing the Impact of Open Road' is the result. Sarah is an expert on the study and treatment of substance misuse and addiction, working with male offenders, women in hostels and young people. Read Sarah's paper. If Sarah's paper inspires you to help, you can make a donation here.
