Our Firm

At Campbell Strategies we help our clients navigate the politics and process of government decision-making in the context of business transactions or policy developments.

Whether it’s direct engagement with government decision-makers and influencers, outreach and coalition building with like-minded (or different-minded) stakeholders, targeted and strategic communications – or a combination thereof – we approach each mandate with a fresh lens and a strategic approach tailored to the circumstance. But there’s one constant: thoughtful advice based on research and experience.

A number of factors distinguish us from our competitors. We are seasoned experts in government relations. We have backgrounds in law, business, politics, public policy and journalism. We are quick studies of our clients’ businesses. We bring a research-based approach to all our mandates. We do not delegate work to juniors. We can “go political” but are sensitive to the appropriate time to do so.

Over the years we have built our reputation by providing our clients with wise counsel, straight talk and hard work.  We wouldn’t have it any other way.
