Florentino & Grimshaw LLC

What Florentino & Grimshaw LLC does

Florentino & Grimshaw LLC is a boutique, women-owned management-side labor and employment law firm founded in 2019 and headquartered in Rye Brook, New York. The firm represents employers of all sizes — both for-profit and not-for-profit — across multiple industries including non-profit, healthcare, financial services, defense contractors, media, and education. Its core practice areas cover investigations, labor relations (including unionized workforce counseling and collective bargaining), litigation and mediation before federal, state, and local agencies and courts, strategic advice and compliance throughout the employment lifecycle, and interactive training programs. The firm's geographic footprint spans New York State (including New York City and Westchester County) and New Jersey.

The firm operates a pure professional services model, billing clients on a per-engagement basis for legal services with no publicly disclosed pricing. The firm has no proprietary technology platform, and there is no evidence of AI/ML technology development; its competitive differentiation rests on talent credentials (former Simpson Thacher & Bartlett LLP attorneys, multiple federal appellate clerkships) and deep multi-jurisdictional regulatory expertise. Distribution is direct, via attorney-client relationships established through phone, email, and in-person consultation, supported by a professional website and a recurring client alerts blog, with revenue likely augmented by professional referrals within the legal and HR community.

The team consists of 7 attorneys: Managing Member Tonianne Florentino (30+ years of employment law experience), Member Kristina Grimshaw, Member Amanda Baker, Senior Counsel Kelly Jines, and Associates John Culhane, Rachele Lena, and Kate Townley. The firm is independently owned with no parent company, no institutional investment, and no public trading. Strategic emphasis has been on associate hiring to broaden capabilities — including M&A employment diligence and AI-in-employment advisory — while incrementally expanding into New Jersey engagements.
