Origin and Background
The Glennon Law Firm opened its Brooklyn office in January 2025, expanding a Rochester-founded practice into New York City, per the firm’s own announcement and an independent report from the Greater Rochester Chamber of Commerce. “This new office is part of our continuing growth plan to serve more clients across New York state,” founder and CEO Peter J. Glennon said at the time. The Brooklyn office, at One Pierrepont Plaza, was confirmed against the firm’s own site and independent business listings.
What Makes This Firm Structurally Different
Glennon Law Firm is not purely reactive litigation counsel; per its own site, the firm is “among only a handful of litigation firms with a commitment to working proactively with clients to prevent against risk” before disputes escalate, leveraging courtroom experience to advise business owners on avoiding litigation in the first place. Several of the firm’s attorneys previously clerked at the state or federal trial and appellate level or practiced at large international law firms.
Practice Areas
- Business litigation and breach of contract
- Partnership disputes
- Fiduciary duty and shareholder disputes
- Non-compete agreement litigation
- Employment litigation
- Trust and estate disputes

Recognition
Peter Glennon has been selected for inclusion in The Best Lawyers in America in the practice area of commercial litigation for nine consecutive years, per the firm’s own announcement, a peer-review-based national survey distinct from a purchased marketing placement. New York does not maintain a board-certification system for business litigation comparable to Texas’s TBLS, so Awesome Attorneys does not apply “specialist” language to any New York business litigation attorney on that basis.
New York Legal Backdrop
Commercial contract disputes in New York generally carry a six-year statute of limitations under CPLR § 213(2). Breach of fiduciary duty claims among business partners or corporate officers may draw on New York’s Business Corporation Law or Limited Liability Company Law, depending on the entity’s structure, alongside common-law fiduciary principles. None of this is legal advice; a specific business dispute should be evaluated by a licensed New York attorney based on the actual facts involved.
Awesome Attorneys Assessment
Glennon Law Firm’s clearest differentiator is a founder with nine consecutive years of Best Lawyers recognition in commercial litigation, paired with a stated proactive-risk-prevention approach rather than a purely reactive litigation model. The honest trade-off is that the Brooklyn office is a relatively new expansion (opened January 2025) of a firm headquartered in Rochester, and Awesome Attorneys could not locate a published, itemized outcomes record or a set of individually attributed client reviews for the New York City office specifically. For a Brooklyn or NYC-area business client who wants an attorney with genuine peer-recognized commercial litigation standing and a preventive, risk-focused advisory approach, that combination is a reasonable basis for a shortlist.
Methodology and Sourcing
This profile was researched from The Glennon Law Firm’s own website, including its New York City and business litigation practice pages, an independent Greater Rochester Chamber of Commerce report on the firm’s NYC expansion, and independent business directory listings confirming the Brooklyn office address.
