Annie's journey began in Vietnam, where at just 13 years old she left everything she knew behind, crossing the South China Sea in a small boat with 33 strangers in search of safety. After time in a Hong Kong refugee camp, she arrived in the UK alone and was placed at Hampton Court House, a children's home in Surrey, where she spent the next five years building the foundation — educationally and emotionally — that would shape the rest of her life.

What's remarkable isn't just what Annie survived, but what she built from it. Rather than letting adversity define her, she made a deliberate choice early on to cultivate a positive mindset and take ownership of her own future. That mindset carried her through Queen Mary University of London, where she earned a BSc (Hons) in Mathematics, and through years of balancing work and evening study to qualify as a tax professional.

In 1998, at just 27 years old, Annie co-founded her first company, ATA Sunrays Ltd — an accountancy and tax advisory firm affiliated with ACCA and ATT. Today, over 25 years later, she is CEO and Co-Founder of ATA Sunrays and has grown into a serial entrepreneur with a portfolio spanning accountancy, lending and property investment, building businesses in London.

But ask Annie what drives her, and she won't point to the titles or the awards. She'll tell you it's about people — keeping them inspired, involved and interested. It's a philosophy she lives by every day, in business and in life: our beginnings don't define our future. Our mindset, the people we surround ourselves with and our determination to keep going shape what comes next.
