Susan Allen began her career in hospital pharmacy, and then as a teacher practitioner at Brighton University. She has produced many CPD articles and packages for health-related and wider audiences. She worked as a senior lecturer at the Leicester School of Pharmacy for 20 years, where she developed her own model for consultation and an online skills evaluation and development programme. Susan began working with Jackie Robinson and her co-researchers, the Asperger's Consultation Group, following their presentation of the 'Triad of Understanding' at a teaching and learning conference in 2014. Susan and Jackie embarked on a mission to improve the communication between pharmacists and autistic people, knowing that this would be applicable to other professions. The 'Triad of Understanding' is the legacy of Jackie Robinson who sadly died in 2018 and is the foundation and motivation behind this guide.
