Who We Are

Recognized both nationally and internationally for delivering results on high stakes, complex litigation throughout the United States, Campbell Conroy & O’Neil, P.C. will provide you with vigorous and aggressive representation to achieve success.

The definition of success varies with each client and with each case and we make it a priority to understand your business goals in order to achieve outcomes that align with your overall strategy. Campbell Conroy & O’Neil, P.C. combines the power of a winning team with the agility to respond quickly and incisively to every problem. Campbell Conroy & O’Neil, P.C. have successfully tried hundreds of large-value, high-exposure, technically complex cases to verdict, on both a national and regional level, a number matched by only a select group of firms in the country. We are in the courtroom on a regular basis and unrelenting representation of our clients is second nature. When the stakes are high, you need attorneys with a voracious desire to deliver a win and a track record to back it up. You need Campbell Conroy & O’Neil, P.C.


When you’re faced with an impending trial, it’s good to know someone’s got your back. The depth of our courtroom experience allows us to work each case with the entrenched efficiencies that come from decades of successful trial work and combine those with the attention to detail, intense preparation and dogged persistence that wins cases.

As our client, you will work closely with the senior trial lawyer in charge of your case and will have access to that lawyer at all times. When appropriate, associates and paralegals will perform the work to avoid higher costs. Our associates bring the same passion and dedication to each case as our most senior trial lawyers. We are committed to the successful resolution of every case; however, not every case belongs in court. We are counselors as well as advocates: throughout the course of our representation, we advise and counsel clients about the relative risks, costs and benefits of continued litigation rather than settlement. Sometimes, mediation is the better course of action. For those clients interested in finding resolution short of trial, the very credible threat that Campbell Conroy & O’Neil, P.C. presents is often enough to settle even difficult cases to the clear advantage of our clients.


In today’s economic climate, it’s all about value. The game has changed: the Association of Corporate Counsel, through the ACC Value Challenge, has proposed a new paradigm for outside counsel relationships, and we’re listening. With responsibility for an important cost center within the company, it is the job of General Counsel to obtain the best results at the lowest cost – and Campbell Conroy & O’Neil, P.C. delivers.

Worry-free Billing and Reporting

We will work with you at the outset to ensure our billing and reporting arrangements match your expectations and make sense within the context of your business. Each client has different requirements and we are happy to schedule reports and format bills to suit your needs.


Up Front Budgeting

As a client, you want both flexibility and predictability around legal bills. While some degree of uncertainty naturally surrounds every case, when required, we can provide a litigation plan and budget to help forecast projected costs. We will revisit these with you on a regular basis and make sure to keep you informed of material changes.


Alternative Fee Arrangements

We have worked with many clients to create alternate fee arrangements, including fixed fees on a regional, national, specialty, or per case basis, and would be pleased to discuss an alternative fee arrangement that provides the best value for you and your business. Our past experience allows us to discuss various options or frameworks if you so choose.

When To Call

Trials are unpredictable and timetables nearly impossible to nail down. Sometimes you may not know you need us until the last minute – that’s ok. Clients have called us to step in at all stages of a trial, and while it’s more efficient to take advantage of our talents at the beginning, we can successfully take over at any point in the process.

For example, when Camp Robin Hood called on us just before trial was set to begin and previous counsel left us with no experts and very little useful material, we rolled up our sleeves and delved into the facts to produce credible evidence in support of our client and presented it to the jury in a way that left no doubt but to rule in favor of the camp. If necessary, we can work seamlessly with your existing outside counsel who may require the depth of hands-on trial experience found only at Campbell Conroy & O’Neil, P.C. Our substantial appellate practice handles cases previously handled by other lawyers in the firm or as special appellate counsel in cases handled by other firms. Campbell Conroy & O’Neil, P.C. have won significant victories on appeal either upholding verdicts in our clients’ favor or reversing adverse rulings.


Our reach has expanded nationally and we act as regional or national coordinating counsel for a number of Fortune 500 companies. We encourage you to explore our site to learn more about our people, our expertise and our clients.
