As senior director of Product Management at Finastra, Mary Kay Theriault plays a central role in shaping the company’s end-to-end digital mortgage solutions. With more than 20 years of industry experience, Theriault leads with a deep understanding of the full mortgage lifecycle — from application to servicing — and brings that perspective to every innovation her team delivers.
Over the past year, she has driven major enhancements to Finastra’s Originate Mortgagebot POS and Mortgagebot LOS platforms, with a focus on automation and workflow efficiency. Under her leadership, the team launched intelligent features that extract and route critical documents — such as income verifications, credit reports and appraisals — directly into imaging systems. These updates have reduced manual touchpoints, improved accuracy and helped lenders increase throughput at a time when speed and cost-efficiency are more critical than ever.
Theriault’s strategic vision ensures product development is aligned not only with Finastra’s goals but with the real-world needs of financial institutions. Her collaborative, user-focused approach has earned the trust of clients and colleagues alike. She regularly engages with banks and credit unions to integrate best practices into Finastra’s roadmap, ensuring solutions remain scalable, compliant and centered on borrower experience.
Colleagues describe Theriault as a steady, thoughtful leader who bridges product design with customer success. Her work reflects Finastra’s mission to “Innovate Finance Together” — not just as a tagline, but as a guiding principle. Behind the scenes, Theriault is building the tools that help community lenders compete, grow and deliver exceptional service at every stage of the mortgage journey.
