David D. Holahan


David D. Holahan is a Partner in Tannenbaum Helpern's Litigation and Dispute Resolution practice. He represents clients in federal and state court actions and arbitrations in a broad range of complex commercial litigation matters, including securities, class action defense, antitrust, regulatory investigations, partnership disputes, breaches of contract and fiduciary duty, fraud, libel, business torts, products liability, RICO and employment disputes. Dave regularly represents both the entities and principals of hedge funds, private equity funds and venture capital funds.

Dave has extensive trial experience at the state and federal levels, including in the Commercial Division of New York’s Supreme Court, New York County, and also has experience representing clients before federal and state regulators. Most recently, Dave secured a complete victory for his client in a dispute between two joint venture real-estate development partners after completing a 23-day bench trial in New York County’s Commercial Division and authoring the post-trial brief.

A zealous advocate for his clients, Dave is particularly adept at developing overall litigation strategies and, where advisable, advising clients regarding litigation avoidance, such as resolving business disputes through negotiation and mediation. He is skilled in working efficiently on behalf of his clients by quickly assessing potential liability and exposure, including the viability of any available claims and defenses. Where appropriate and necessary, Dave has utilized his broad experience in structuring varied agreements with outside litigation funding firms, enabling his clients to litigate or arbitrate meritorious claims that would otherwise be lost because the client was either unable or unwilling to pay for the expense of litigation.
