Tax, accounting,
and advisory —
practiced with care
since 1985.
Bonnie & Herrera, CPAs is a small Orange County firm built on three principles we have not changed in forty years. Professionalism. Responsiveness. Quality. The rest is detail.
A full-service firm, attentively staffed.

Our reputation reflects the
standards we demand of ourselves.
- I.
Professionalism
Every client receives close personal attention. We treat the smallest engagement with the same care as the largest. Respect is the table stakes of our practice.
- II.
Responsiveness
Calls and emails returned the same business day. We anticipate client needs before they become urgent — that has been our standard for forty years.
- III.
Quality
Our reputation reflects the standards we demand of ourselves. We continue our education year over year so our advice meets the moment, not the prior decade.
We earn the work,
and we keep earning it.

Big-Four-trained partners, small-firm attention
Our principals bring fifteen-plus years of Big Four and regional-firm experience to a practice small enough that you know who is touching your return.
- 02
California CPAs, licensed and current
Every partner is a Certified Public Accountant licensed by the State of California and a member in good standing of the AICPA.

Forty years in Anaheim Hills
Founded in 1985. Three principal owners. A team that has weathered every tax-code rewrite and stayed close to its clients through each one.
- 04
Built around closely-held businesses & high-net-worth families
From multi-entity corporate returns to trust and estate planning, we work where personal and business finances overlap — and where the planning matters most.
Tax season approaches. Reserve your engagement before our calendar fills.
New-client onboarding takes thirty to sixty minutes by phone or in our Anaheim Hills office. Bring last year's return and recent financials. We will tell you, candidly, whether we are a fit for your situation.
Seven specialists. One small firm.
Our partners and staff bring a combined century of practice to every engagement — Big Four, regional, MBA, MST, and ProAdvisor credentials, applied with the attention only a small firm can afford.
