What we’re about

We’re here to help you build meaningful, sustainable success; your way.

The kind of success that performs in real life.

We think strategically.
We move with intention.
And we take action that actually moves the needle.

Big vision matters here; supported by clear decisions, strong systems, and leadership that can hold what you’re building.

You get to design both your business and your life on purpose.
We’re here to help you do that with clarity and momentum.

Nice to Meet You

I’m Tash.

I work with business owners who want to grow with clarity, confidence, and intention.

My background spans policing and law, high-performance sales, leadership training, and business ownership. I’ve built three businesses to multi–six figures, sold multiple millions, and supported hundreds of people through leadership and performance development.

I bring a strategic lens, grounded perspective, and a deep understanding of what sustainable performance actually requires.

This work is underpinned by my proprietary Performance Chain Model, which recognises that results follow behaviour, behaviour follows thoughts and emotions, and those are shaped by inner capacity.

This philosophy guides everything I do; inside Business by Design and beyond.
