Anton Prokopenko, MBA, CPA, CFP®, EA
MBA · Business strategy CPA · Tax & accounting CFP® · Financial planning EA · IRS-licensed
Anton specializes in retirement planning, business tax strategy, and personalized financial advice designed to reduce taxes and support long-term financial goals. Whether you’re a solo entrepreneur, a growing practice, or planning for life after work, he delivers clear, actionable guidance tailored to your situation.
Most advisors specialize in either taxes or investments. Anton holds the credentials and the responsibility for both — which is what lets Sansone coordinate the two sides of your financial life under a single strategy.
“If your CPA and your advisor don’t talk to each other, you’re paying for two opinions that might contradict each other. I’d rather give you one full opinion.”

Common questions
Working with a CPA & Certified Financial Planner® professional:
Where is your office in Crystal Lake?
Our office is at 850 S McHenry Ave, Suite D, Crystal Lake, IL 60014 — nearby Crystal Lake South High School off of Randall Road. We meet clients across McHenry County and offer virtual meetings for those who prefer them.
What does "fee-only fiduciary" actually mean?
Fee-only means we're paid only by our clients — never through commissions on the products we recommend. As a fiduciary, we're bound to act in your best interest at all times. This structure removes the conflicts of interest common in commission-based advice.
Do you handle both taxes and investments?
Yes. Anton holds both the CPA and CFP® credentials, so tax planning and wealth management are coordinated under one relationship — rather than split between two professionals who never speak to each other.
Who do you typically work with?
Retirees and pre-retirees with meaningful retirement savings, and small business owners across McHenry County who want their tax strategy and investment plan working together.
