Cory G. Litzenberger, CPA, CMA, CFP, C.Mgr

CEO | Director, Canadian Tax Advisory
  • 403-986-3829 ext. 100

With the Income Tax Act always by his side on his smart-phone, Cory has taken tax-nerd to a whole other level. His background in strategic planning, tax-efficient corporate reorganizations, business management, and financial planning bring a well-rounded approach to assist private corporations and their owners increase their wealth through the strategies that work best for them.

An entrepreneur himself, Cory started CGL with the idea that he wanted to help clients adapt to the ever-changing tax and economic environment and increase their wealth through optimizing the use of tax legislation coupled with strategic business planning and financial analysis.

His relaxed blue-collar approach in a traditionally white-collar industry can raise a few eyebrows, but in his own words: “People don’t pay me for my looks. My modeling career ended at birth.”
