Tracy Nyamuda
As a pastor, pharmacist, and NBI practitioner with more than 20 years of experience, I help couples, parents, and children thrive in their relationships and personal growth. In marriage enrichment, I draw on the proven approach of my husband, Paul Nyamuda-renowned marriage coach and psychologist featured on Netflix’s Saving Our Marriage-to help couples strengthen their connection and mutual understanding. I also equip parents to recognise and respond to their children’s unique thinking preferences, while guiding young people in subject and career choices aligned to their strengths. As a mother of three in high school and university, I bring empathy and practical wisdom to families seeking to flourish.

Kayla Thomsen
I am a Specialist Wellness Counsellor and NBI practitioner with a postgraduate degree in Psychology. I am dedicated to helping individuals gain a deeper understanding of themselves and unlock their full potential. I believe that human beings are profoundly complex and remarkable, and that personal growth begins with self-awareness. Taking time each day to connect with and understand our true selves allows us to live with authenticity and purpose. When we truly know ourselves, we can build meaningful relationships, achieve lasting success, and experience genuine happiness – because all transformation begins with self-understanding.
Marna Botje
I am an Optometrist with a special interest in behavioural and paediatric vision care. I am passionate about helping children understand and use their visual world with confidence and ease. With a Postgraduate Certificate in Education, I combine my background in eye care and teaching to support children who may be struggling at school, not because they can’t learn, but because their visual or thinking processes work differently. Using insights from the Kobus Neethling Brain Institute (NBI), I help children and parents discover their preferential thinking styles. In other words, how they see, process, and respond to the world. By understanding these patterns, we can build strategies that make learning easier, reduce frustration, and help each child reach their full potential – both in the classroom and in life. I believe in working together with parents and teachers so that we can unlock new ways for our children to learn, grow, and thrive. Every child deserves the chance to see – and think – in their own best way.
