The ability to secure resources, in house, to tackle any aspect of legal advice required. The willingness to get involved and provide guidance.

Dedication, responsiveness, understanding, communication skills, team work and of course legal prowess.

BD&P is unique in that it is a single-office practice in Calgary but with deep experience that extends beyond Western Canada. That allows them to be more nimble and flexible, and less bureaucratic, than most of their competitors.

I recently engaged Sean Korney, who is exceptionally bright, very quick to understand the situation and synthesize the main issues and problems and then fully dedicates himself and his team to solving them.

Alicia Quesnel is very experienced, diligent and thoughtful. I would gladly work with her again.

The oil and gas team at BDP is unique in that their experience and expertise is unparalleled and sophisticated, yet very practical and business focused.

BDP’s team is composed of pure experts who can handle the pure legal issues that arise but they are also very business minded lawyers who see the larger picture and that move efficiently and pragmatically to get projects completed.
