Our story

Numbers explained, not just filed

We work with owners who wish they did a better job tracking income and expenses, and who are nervous about mistakes in their books. Instead of handing back a stack of forms, we walk you through what each line means and what to change next year.

Computerized offices and secure online access let us deliver accurate, efficient service at a competitive price — whether you are down the street in West Covina or on the other side of the country.

What guides our work

Licensed and accountable

A California and Missouri licensed CPA signs every return we file — never a seasonal preparer.

Proactive, not reactive

We plan before December so the April bill is already decided, not discovered.

Bilingual service

Fluent in Mandarin, Cantonese and English, serving clients across the United States.

Flat, predictable fees

Quotes up front, all-inclusive packages, and no surprise hourly invoices.
