Our Mission
At Zastenchik & Co. CPAs, we believe your accounting firm should help you look forward —That’s why we go beyond tax prep and reconciliations to offer advisory-first, strategic services designed for you.
Our mission is Proactive Planning and Communication to Maximize the After-Tax Net Wealth of our Clients.

Our Founding
Zastenchik & Co. CPAs was founded by David Zastenchik, CPA, CFP, a Hudson Valley native and licensed CPA. After working in both large firms and business finance roles, David saw a gap between what clients truly need—both business owners and individuals—and what many accounting firms actually provide.
Rather than just filing tax returns or offering generic reports, David built this firm to serve as a long-term strategic partner. For business owners, that means guidance from someone who understands the day-to-day challenges and long-term goals of running a company. For individuals, it means clear, thoughtful tax and financial advice tailored to your unique situation—whether you're planning for retirement, navigating major life changes, or simply looking to keep more of what you earn.
David leads the firm with a focus on clarity, responsiveness, and proactive support. He believes your CPA should help you grow—not just react when deadlines hit
Our Team and Values
We’re a lean, high-touch CPA firm that works across the Hudson Valley and beyond. Our clients rely on us for honest insight, responsive communication, and guidance grounded in real experience.
David Zastenchik is more than a CPA—he’s a business owner too. He knows what it’s like to make payroll, juggle client work, and plan for growth. His no-nonsense style and commitment to quality have made Zastenchik & Co. the go-to firm for small businesses that want more than generic service.
Whether he’s leading a quarterly review, troubleshooting QuickBooks, or helping you understand the story behind your numbers, David is focused on one thing: helping you make smart financial decisions that move your business forward.
