Founder Background
Pastia CPA builds on Alex’s work through BRICKBASE, the CFO advisory business he founded in 2013. That work combined accounting, internal controls, financial planning, and management reporting. Developing cloud-based workflows added practical experience in financial data management and reporting automation. Today, that foundation powers a practice focused on ongoing disciplined accounting, U.S. tax compliance, and CFO advisory, driven by repeatable systems that gain efficiency over time.
Learning from Large Scale
Alex’s consulting and advisory experience spans a global roster of complex organizations, including Bunge, Frankfurt International Airport, Lufthansa, Magna International, Maple Leaf Foods, Nissan Renault, OMERS, Panasonic, and Zeiss. That large-scale institutional rigor directly informs his work with privately held businesses and partner CPA practices.
