Ultimately, Taz loves what she does and that Is why she excels at it. Taz maintains she would not have been able to achieve all of this without the solid foundations of Onfit and other course providers.
These achievements are the result of Taz refusing to accept that her circumstances or other people’s actions or words would dictate her future. Taz is a domestic violence survivor who had to start her own business to facilitate her and her children’s escape from an abusive partner/ father. As a mother, the responsibility to protect her children meant she did not have the option for her business not to work, it had to work. Your health and happiness truly are a wealth beyond any monetary value and if Taz could offer any advice to business women it is to ensure your priorities and self worth are unwavering. As a mother, your children are the greatest work you will ever do- be appreciative for that gift and ensure they feel valued every day. For all of the challenges that come with “motherhood joys” - your children are your greatest assets. They teach us patience, multitasking, open-mindedness, negotiation and forgiveness. Tazs business success is a tribute to her children, Kai and Raven, being the amazing teachers that they are.
