More About Me
I know the struggle firsthand. For years, I tried to overcome my perceived weaknesses, and still felt like I was falling short.
The turning point came when I stopped trying to fix myself and started understanding my ADHD brain. I learned how executive function challenges quietly shaped my daily life, so I could address problems at their root instead of endlessly firefighting symptoms.
That’s why my coaching goes beyond surface level strategies or quick tips. We’ll dig deep to understand your unique wiring, build systems that truly fit, and create changes that last, not just a temporary relief, even when life gets messy.
I work with clients worldwide in English or Japanese. Originally from Japan, I’ve lived in the UK for 20 years, and raised two teenagers. I understand the complexities ADHD can add to family life and how healing can start with you, spreading powerful change that ripple outward and transform relationships.
Are you ready to uncover what's holding you back? Let's revolutionalise the way you live, turning obstacles into opportunities and your unique brain into your greatest asset!
"As a parent of 2 young adults with ADHD, I often brought issues to coaching where I was struggling to work out the best way forward. Sometimes the issues were just my own challenges.
Sumiko always showed me great compassions and understanding and combined this with gentle but skilled expertise in coaching. It was so helpful to have her support to help me explore my own situations and identify my own solutions."
