Having joined the Marines aged only 16 and passing the elite Commando training first time despite being the youngest member of the troop and suffering with a lifelong stammer, David knows first-hand how to persist until you succeed, never succumb to the option of failure, and the mindset that is required to achieve that. During his life, David was living with such a crippling fear of talking due to his stammer, he declined phone calls, only communicating via text message, he had to raise his hand in the register at school as he could not say his own name, and he was also told he could not promote any higher in the Military or attend courses which included the use of Radios due to his severe speech impediment. 

After battling with a severe stammer his entire life and the knock-on mental effects of this, David persisted to work on his speech until the stammer was all but gone, and then go full circle in the recovery of this by pushing himself into the public speaking sector to inspire others with speech impediments that it can be done and through persistence and perseverance anyone can learn to talk again and go on to achieve greatness in the face of adversity. David now speaks stammer-free and is using his newly found voice to show the world that anyone can overcome their greatest fears and adversities by harnessing the ‘Non-Quitting Mind’ and through utilising ‘Hope with Hard Work’, two of David’s topics that teach people practices to implement into their own lives to deal with their personal challenges and struggles.
