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.”
