What Our Clients Are Saying
Real results from real clients. Names and details have been changed to protect privacy, but the savings are 100% accurate.
I'd been with the same CPA for eleven years and assumed I was in good shape. Auxilium found over $80,000 in annual savings within two weeks. The implementation was seamless and completely defensible. I wish I'd done this a decade ago.

A Message From Our Founder
My name is Natasha Dornbush. I spent the first decade of my career as a tax attorney inside the IRS — and what I saw changed the way I think about this industry forever.
Year after year, I watched physicians, dentists, and business owners hand over six-figure sums that they were never legally required to pay. Not because the system was rigged against them, but because no one in their corner understood the rules well enough to use them. Most of the professionals I encountered had trusted advisors who were competent at compliance. What they lacked was a strategist.
I founded Auxilium with one belief: that the tax code, properly understood, is not a burden — it is a toolkit. Our job is to know every tool in that kit and put it to work for the people who've earned it most.
We are not the right firm for everyone. We are the right firm for the professional who has built something real, who is tired of reactive advice, and who is ready to treat tax strategy as the serious financial discipline it is.

⎯⎯ ABOUT AUXILIUM
Not Your Average Tax Firm
The word auxilium is Latin for "help" — specifically, the kind of help that turns the tide. That's precisely what we provide. While conventional accountants react to history, we engineer the future.
Auxilium was built on a foundational belief: that the tax code was designed to incentivize specific behaviors, and that sophisticated professionals deserve advisors who understand how to use every legal tool available. The difference between a great tax plan and a basic one is measured in tens of thousands of dollars annually — compounding for a lifetime.
Our team combines credentials across tax law, financial planning, and accounting — working together on every client engagement. We are not a volume shop. We deliberately limit our client roster to ensure every client receives senior-level attention.
"Most professionals overpay their taxes by $50,000 to $200,000 annually — not from fraud, but from a lack of proactive strategy."
⎯⎯ COMMON QUESTIONS
Frequently Asked Questions
We believe in radical transparency. Here are honest answers to the questions every prospective client asks
Most CPAs are compliance professionals — their job is to accurately report what happened. We are strategy professionals. Our job is to architect what will happen so that your tax liability is minimized legally and substantially. A typical CPA might save you 2–5% on your effective rate. Our strategies routinely deliver 8–15% reductions. We don't replace your CPA — we enhance your entire advisory team.
Every strategy we implement is 100% grounded in the Internal Revenue Code, IRS regulations, and case law. We do not engage in aggressive positions that cross ethical or legal lines. In fact, because our documentation and compliance protocols are so thorough, our clients typically have lower audit risk than average. Every plan is reviewed by our in-house tax attorney before implementation.
The initial Tax Opportunity Assessment is completely free. We review your prior two years of tax returns, analyze your entity structure and income profile, and provide a written summary of every strategy available to you — including the projected dollar value of each. There is no obligation to engage us after the assessment. We want you to see the opportunity clearly before making any decision.
Our strategies typically create the most significant impact for individuals and businesses with $300,000+ in annual income, though we regularly work with clients earning $200,000+ when practice ownership, real estate, or complex entity structures are involved. The free assessment will tell you definitively whether advanced tax planning makes financial sense for your specific situation.
Not necessarily. Many clients retain their existing CPA for compliance work while engaging Auxilium exclusively for strategy and implementation. We are experienced at collaborating with other accounting professionals and view ourselves as an enhancement to your existing advisory team, not a replacement. If your situation calls for a full transition, we can discuss that as well — but it is never a requirement.
Many clients experience savings in the same tax year they engage us, often within 60–90 days of implementation. The assessment phase typically takes 1–2 weeks. Strategy development takes another 2–3 weeks. Full implementation timelines vary based on complexity, but we move with urgency — every day without your plan in place is a day of potential savings lost.
