A Third-Generation Accounting Firm Built in Lynbrook


Hirsch & Hirsch CPA PLLC has been part of the Lynbrook community for over 50 years. What started as a single-practitioner office has carried through three generations of the Hirsch family, and the same standard of personal service that defined the firm from the beginning still defines it today.


We operate out of one office with one team.


There's no franchise structure, no seasonal rotation of preparers, and no hand-off to someone you've never met. When you work with Hirsch & Hirsch, you work with the same CPAs from your first call through every filing that follows.
