“I’m fully invested in creating an environment where you emerge from my course with not only an understanding of payments risk management and best practices, but also a newfound confidence in how you can apply what you’ve learned to grow in your role and your career.”

As Director of Risk for Visa in the Middle East and North Africa, I am responsible for managing payments system risk. I work with banks, merchants, governments, regulators, law enforcement agencies and other key stakeholders to ensure the payments ecosystem remains secure, and that cardholders, banks and merchants alike benefit from the advantages of digital payments.

My payments experience includes business development, risk management, dispute resolution and project management. Prior to joining Visa, I spent 10 years in Tunisia working for Banque Nationale Agricole, which included serving as a fraud and dispute manager. I have a degree in marketing and a Master of Business Administration in bank management, and am fluent in Arabic, French and English (and am working toward fluency in Spanish).

“When I teach a class, my most important role is to facilitate conversations between you and your classmates so you can share real-life experiences and gain perspectives from different markets. My goal is that you not only learn something new and relevant to your role, but that you also take away ideas and inspiration to improve your performance — and the performance of your organization.”

As Training Manager at Visa, I deliver courses to our clients around the world. I’m also the instructor champion for a number of Visa University courses, where I review current global trends and Visa processes to ensure the content I teach remains relevant in our ever-changing industry.

I have practical experience in both the operational and business management aspects of banking and financial services, which includes 18 years in training, learning and development. I am an accredited career coach who enjoys travel, technology and music, and I’m currently learning how to play the guitar.

Mary Pat McMahon
Head of Global Debit, Visa
  • Years in the payments industry: 30

"When you attend my course, I would like you to gain a deeper understanding of debit, a payments product that continues to show significant success in competing for cash and check spend. After covering the basics – the market landscape, debit user characteristics and issuer business case, I will leave you with some best practice recommendations for accelerating growth in your own debit portfolios."

As Head of Global Debit at Visa, my team is responsible for driving the global growth and evolution of Visa’s debit product offerings, which generate over $3.5 trillion in annual payment volume globally. Prior to this role, I was responsible for managing the Visa Debit product for the U.S. and for driving growth in Visa’s U.S. debit issuer portfolios.

Before Visa, I spent time in senior roles at Bank of America (Interactive Banking Division) and at Cash Station (now Star), a regional ATM and Debit POS network that served the Chicago metropolitan area. My first role in payments was to take the Cash Station ATM network to the point of sale — the first implementation of debit for that market and a fantastic way to learn the “nuts and bolts” of the business. I received a Bachelor of Arts in American Studies from Georgetown University and a Masters of Management in marketing and finance from the J.L. Kellogg Graduate School of Management at Northwestern University. Residing in the Bay Area, I enjoy spending family time with my husband and three teenagers — playing sports, traveling to new and interesting countries, and discussing current events over the dinner table.
