Booking a speaker for September's mental health dates
World Suicide Prevention Day and World Alzheimer's Day both fall in September, and organisations often mark them with an internal talk or panel rather than a poster campaign. A typical format is a 45-60 minute keynote or fireside chat, followed by audience Q&A, run either in person or virtually for distributed teams. For World Suicide Prevention Day, Natasha Devon MBE, a mental health campaigner, author and broadcaster, and Hayley Mulenda, a Gen-Z voice and mental health advocate, both speak on building genuinely supportive workplace cultures. Owen O'Kane, a former NHS lead therapist and wellness expert, is a strong fit for either date, drawing on his clinical background to give practical, evidence-based guidance rather than generic wellbeing platitudes.
