An Established Reputation in Complex Business and Energy Litigation and Appeals

Pierce & O'Neill, LLP is a litigation “boutique” with a single focus — the devoted representation of clients in significant litigation. There are major differences between litigators who engage primarily in motion practice and those who try cases. We are a firm of trial lawyers. We excel at litigation and appeal.

Our reputation has been built upon results that exceed expectations and our responsive, innovative and common-sense advice. The relentless pursuit of our clients’ interests fosters a spirit of cooperation and partnership. We undertake substantial matters on a regular basis for both new and existing clients and place a significant value on our longstanding relationships with our clients, many of which span several decades.

Vast and Comprehensive Courtroom Experience

Both Jesse Pierce and Jack O’Neill have more than 40 years of courtroom experience trying cases and handling appeals. Although most often retained at the outset of a matter, the firm is frequently asked to substitute as trial counsel, or to step in as appellate counsel. The firm is widely regarded by clients and peers alike as a “Go-To Law Firm” for high stakes, complex business and energy litigation.
