Most business owners find out what they owe in April. My clients know in January — and they've already done something about it. That's the difference proactive accounting makes.
These aren't hypothetical. They're the exact things my clients said before we started working together.
No long contracts. No confusing intake forms. Just three steps to go from overwhelmed to completely covered.
Takes under 60 seconds. Create your secure client portal account and reach out directly — no commitment, no pressure. I'll respond personally.
Free · 60 SecondsWe talk through your situation — your business, your goals, what's been stressing you out. I'll tell you honestly what you need, and whether I'm the right fit.
No Pitch · No PressureOnce we're working together, you'll have a financial partner who's always looking ahead — proactive planning, clean books, and zero April surprises. Every year.
Year-Round Coverage"Every business owner deserves a trusted financial partner — not just a tax preparer."
I'm Brandon Mondragon, founder of Mondragon Tax & Advisory. I'm a solo practitioner based in San Diego, CA — which means when you work with me, you're always talking directly to me. Not a call center. Not a junior associate. Me.
I serve individuals, rental property owners, and small businesses across California and nationwide — handling everything from monthly bookkeeping and payroll to proactive tax planning and entity strategy. My approach is simple: I stay ahead of problems so you don't have to deal with them.
Flat monthly rates — no billable hours, no surprise invoices. Tax return services are priced separately and available to everyone.
This isn't a drop-off-and-file service. Every return I prepare includes a personalized advisory package — specific notes, findings, and action steps tailored to your situation. You'll understand exactly what was filed and why, plus what you can do differently going forward.
I don't skip over details that might affect you, and I don't mention things that don't apply. What you get is a thorough, precise review of your tax picture — and a practitioner who will follow through with you throughout the year.
Final pricing is always confirmed before work begins. No surprises.
Testimonials coming soon. In the meantime, reach out directly — I'm happy to connect you with past clients who can speak to their experience.
