“Philippa Waller and Penelope Waller at 4D HumanBeing always deliver high quality, professional sessions that have a lasting impact that drive action at the individual and collective level. Most recently “The Big Energiser” gave our People Leaders in Cisco’s Global Security Sales Organisation something they could each take away to help their own resilience and wellbeing during this pandemic. Always a pleasure to work with and we will no doubt be doing so again soon!”
