Holly Parkes and Greg Johnson are two of the most purpose-driven people you’ll ever hear from.


Holly Parkes first came on the podcast during one of the toughest times of her life, sharing what it was really like trying to support someone battling a serious brain injury and searching for answers that never seemed to come. Greg is a former NZ SAS operator who spent years exposed to explosive blasts, before discovering his own brain injury had been misdiagnosed for years.


Together, they are now doing incredible work helping players, veterans, and everyday people who have struggled with brain injuries


From believing there was no hope to discovering a clinic that is actually helping people recover, this conversation is full of knowledge, and deeply important.


In this episode we dive into:


- Greg’s SAS career and how repeated blast exposure damaged his brain

- Being misdiagnosed with mental health issues instead of brain injury

- What brain injury actually does to your body, energy, personality and relationships

- Why so many athletes and veterans are slipping through broken pathways

- How Holly desperately searched for help and finally found a clinic doing things differently

- The Brain Health & Biofeedback Clinic in Dunedin and how it works

- Real people they are helping right now and the changes they’re already seeing

- Why brain injuries are not a death sentence

- What needs to change in sport, medicine, and support systems

And heaps more.


As you'll hear these two are super passionate about this topic which I know is a topic of relevance for many. The best thing about this episode is that if you are concerned or worried about your head there is hope!
