A Full-Service Ottawa Law Firm Founded on Integrity, Focused on Solutions

Trusted Lawyers for Business, Real Estate, Employment, Estates and Personal Injury

Tierney Stauffer LLP has been a trusted fixture in the Ottawa legal community since 1982. We have dedicated ourselves to providing exceptional legal representation to clients throughout the greater Ottawa area in a wide variety of practice areas. Our lawyers have deep roots in the area; we all live, work and raise our families here. As a firm, we are invested in providing our clients and our community with friendly and straight-forward service while offering consistently exceptional legal representation.

The firm was founded on a set of core values that we still strive to live by every day; namely, integrity, excellence and professionalism. These values remain as important to us now as when we began. We take pride in the long-term relationships we continue to build with both individual and corporate clients through our dedication to prioritizing responsiveness and accountability. Each of our lawyers aim to maintain a high standard of excellence in both the work we do and the results we achieve, which is reflected in our decades of success and growth in the community.

The Expertise of a Boutique Law Firm with the Resources of a Full-Service Law Firm

At Tierney Stauffer LLP, we offer expertise across a wide range of practice areas. We combine the breadth of legal services of a general practice firm, with the depth of knowledge and area-specific focus of a boutique establishment.

Tierney Stauffer LLP has created dedicated practice groups for specific areas of law:

Many of our lawyers, and at least one from each practice group, have over three decades of experience working in their respective fields. This level of experience, combined with the wealth of knowledge that decades of practice brings, results in strong, effective and timely representation for our clients.

When legal issues intertwine and overlap across multiple areas of law, our practice groups work collaboratively to provide comprehensive counsel. This integrated approach allows for a broader consideration of the issues at hand while addressing any possible related issues in other legal areas in the future.

Further, the size of our team means that our lawyers represent a broad range of experience and seniority. However, the senior members of our legal team regularly share their expertise with our newer lawyers, allowing us to offer a consistently exceptional level of service to our clients at a variety of price points.

Personal Injury Lawyers Focused on Effective Solutions

Being injured in an accident of any kind is a traumatic experience and can be devastating for both the injured person and their loved ones. It is essential to have a strong support system as the stress of dealing with the aftermath of a serious accident can quickly become unbearable.

Tierney Stauffer LLP has a large practice group dedicated to finding comprehensive solutions for personal injury victims. We take a unique approach to personal injury law, focused on ensuring compensation that factors in the life-long needs of injured clients. While some firms are financially motivated to settle quickly, we are motivated to settle soundly. Hasty settlements often result in short-term gains at the expense of long-term security, leaving clients reliant on insufficient civil damages to manage long-term health and medical expenses.

With over 35 years of experience, our team of Personal Injury lawyers represent clients in a variety of personal injury matters, including:

Decades of Dedication to Our Communities

Our reputation as a firm that clients love to work with, and trust implicitly is of utmost importance to us. We are known for providing clients with honest and fair representation; principles we live by day to day.

We work closely with the Ottawa business community, and one of our founders and senior corporate lawyer, Stephen Tierney, is a trusted advisor to several local businesses. Another one of our founders, Ian Stauffer, is a Certified Specialist in Civil Litigation and has used his expertise in this area to serve the community as a judge and administrator at the local small claims court for a number of years.

Our firm and our entire team are committed to working to better the local communities we serve through our active involvement with charitable organizations including Ottawa Lawyers Feed the Hungry, the Children’s Treatment Centre in Cornwall and the Brain Injury Association of the Ottawa Valley.
