'In March 2020, everyone’s life went into a spin. Being a business owner, entrepreneur, investor, speaker and coach, my business model was turned on its head. I was introduced to John through a mutual business owner. John’s ability to listen deeply, pick up on what was being said and more importantly, what wasn’t been said, helped immensely with establishing a new route to success! His straight talking, action oriented, solution focused style empowered me to create opportunities to succeed. He held me accountable and challenged me at the right times to make sure I was able to operate at the high performance level that I’m accustomed to!'
