Our Dna

McNabb & Lucuk LLP is an accounting firm built around one purpose: supporting growth-minded entrepreneurs and organizations in the Peace Region.

We believe that a strong local economy is the product of leaders getting the right help at the right time through the right approach.

The support we offer goes beyond just producing accurate returns and financial statements. Our real value comes from our insights and strategic partnerships.

After all, it’s not just about reporting the numbers. It’s also about improving them.

Our motto (“save, protect, grow”) is also our business model. We leverage our tools and resources to help clients:


  • Save their money (using tax optimization strategies).
  • Protect their assets (through effective structuring).
  • Grow their businesses (by planning with the future in mind).

Our Values

We see things like integrity and competence as minimum requirements. Going beyond the fundamentals, we put a big priority on:

  • Responsiveness (getting back to clients quickly).
  • Approachability (professional, but with personality).
  • Flexibility (working around unique needs and schedules).

Our Leadership

McNabb Lucuk LLP’s founders were originally local partners in a network of accounting firms spread across Northern Alberta. As of January 2015, they decided to split off on their own so as to offer tailored services that match the unique conditions of the Peace Region.
