Janet Wong, CPA
Founder & Principal
San Ramon, California
A calm, comprehensive approach to your financial life.
Janet Wong is a Certified Public Accountant and the founder of HW Accountancy Corporation. She built the firm because business owners and families deserve a thoughtful, year-round advisor — not just a seasonal tax preparer.
Her practice is grounded in a simple discipline: take time to understand each client's situation and goals, then design a plan around them. Tax, accounting, bookkeeping, and business questions are considered together — because in practice, they always affect one another.
Clients describe Janet as attentive, patient, and unusually clear. She explains what the numbers mean, what the options are, and what she recommends — so you can make important decisions with confidence.
A small, senior team — every client knows who is doing their work.
HW Accountancy is intentionally boutique. Janet leads every engagement personally, and the team supporting her is chosen for professionalism, discretion, and consistent follow-through.

Tax, accounting, and business decisions are made together — never in isolation.
Communicate clearly.
No jargon. Just plain-language explanations, options, and a recommendation you can act on.
Own the deadlines.
We track what's due, remind clients ahead of time, and follow up when something's missing.
Stay year-round.
Peace of mind isn't a tax season promise — it's the way we practice all year.
