Our Story

Who We Are

Koblick & Weinstein CPAs P.C. has a rich history rooted in the Westchester County community, originally founded by Alan B. Koblick, CPA in 1985. In 2022, Michael A. Weinstein, CPA — who had built his own successful practice since 2016 — merged his firm with Alan Koblick, officially forming Koblick & Weinstein CPAs P.C., carrying forward the firm's legacy while bringing renewed energy, expanded expertise, and a modern approach to client service. We serve a diverse clientele including individuals, S-Corporations, C-Corporations, partnerships, trusts, and estates across virtually every industry and in all 50 states. At the core of everything we do is a belief that every client deserves a trusted advisor who knows their situation, anticipates their needs, and is accessible year-round — not just at tax time.
