About the Founder

Zahra Qureshi | CPA, CMA

When Zahra Qureshi founded Optinum Professional Corporation in 2018, her vision was to create more than just an accounting firm.  As an experienced Chartered Professional Accountant, social entrepreneur and facilitator, Zahra envisioned Optinum as a leading finance firm in transforming small businesses and non-profits for more robust, sustainable and purpose-driven operations. Her portfolio includes managing complex financial reporting structures, planning and budgeting that empowers strategic decision making, successful fundraising efforts, and innovative social enterprise models.

In 2020, Zahra also founded a not-for-profit organization called the Social Venture Circuit to build a learning community of mission-driven enterprises committed to social, cultural and environmental impact.

When not helping changemakers, you can find Zahra mentoring future CPAs, testing out new gluten-free recipes and exploring world history.
