Dr Lee Warren is a practising neurosurgeon, Iraq War veteran, and author who specialises in the intersection of neuroscience, the mind and faith. Dr Warren advocates "Self-Brain Surgery", a method using our own cognitive awareness to change our mental habits, to heal from trauma, and improve the quality of our lives. Dr Warren shares the story of losing his son to a murder, the moment his world was forever changed. With true lived experience, Dr Warren explains the possibilities that exist for us to make structural changes to our own brain, so it's healthier and less prone to depression, anxiety, grief, worry, and other issues that make us unhappy and keep us stuck.
