Why Koblick & Weinstein

Your Trusted CPAs

When you work with Koblick & Weinstein, you work directly with licensed CPAs who know your financial picture — not a rotating cast of junior staff. Michael A. Weinstein, CPA brings over 17 years of public accounting experience and founded this practice with one goal: to give every client the kind of expert, personalized attention that large firms simply cannot offer. Matthew J. Martin, CPA adds a Big 4 background in tax strategy, business consulting, and financial analysis — ensuring our clients benefit from institutional-level expertise in a boutique setting.

Together, Michael and Matthew don't just prepare returns — they build long-term relationships rooted in proactive planning, honest advice, and a genuine commitment to each client's financial well-being. Whether you're an individual navigating a life change or a business managing complex multi-state obligations, we take the time to understand your goals and develop a strategy built around them.

We also maintain strong working relationships with trusted financial advisors, attorneys, and other professionals — creating a collaborative network that provides our clients with comprehensive, coordinated guidance across every aspect of their financial life. When you need more than a tax return, we make sure you have the right people in your corner.
