Our Story

Built on a Simple Belief: You Deserve Better

I don't usually introduce myself as an accountant — not because I'm not one, but because I see myself first as a business owner, just like you. I know what it's like to run out of cash, manage staff, and juggle deadlines. That's why my approach is different.

I work proactively — monitoring your finances all year round, not just at tax time. I explain everything in plain English (and Spanish), and I respond quickly because I know how important it is to get answers when you need them.

Before starting ASU, I worked for top multinational companies in my home country — including BASF, the number one chemical company in the world. That experience gave me a strong foundation in systems and processes. Since moving to New Zealand, I've spent over 7 years working in the local market, applying global best practices to the unique needs of Kiwi businesses.
