About the firm

A boutique Northeast advisory firm — built around the team.

Grenier Lender is partner-led and multidisciplinary by design. Legal and business backgrounds, entrepreneurial experience, and decades of tax and accounting practice — all working under one roof in Danbury, Connecticut.

Our story

An advisory firm built the way owners actually want to be served.

Grenier Lender was founded on a simple idea: most growing businesses don't need three separate professionals giving three separate answers to the same question. They need one integrated team that understands the business.

That conviction shapes how we work — and who we hire. Our team blends legal training, business education, and operating experience with deep tax and accounting practice, so the conversations we have aren't constrained to compliance.

We're proud to be a member of the Aline Accounting Partners Group — independent, partner-led, and supported by a national network that lets us bring scale without losing the boutique relationship our clients hire us for.
