“Legacy systems don't fail organizations because they're old — they fail because no one left behind the knowledge to evolve them. My job is to make sure that never happens on our watch.”
There is a vanishingly small group of people in the retirement industry who have built a recordkeeping system from the ground up. Tom Nigro is one of them. With over 30 years in retirement technology, Tom possesses a command of the recordkeeping engine that can only be earned by writing it — every transaction type, every downstream dependency, every edge case that sits between a contribution and a participant's retirement security. That depth is what makes him one of the most sought-after technologists in the industry.
At Convergent, Tom leads the team responsible for supporting and modernizing legacy applications across the retirement ecosystem. He has built a remarkable track record of breathing new life into aging, mission-critical systems that had become bottlenecks for entire organizations — untangling decades of technical debt, rearchitecting for modern distributed environments, and retiring legacy platforms cleanly without disruption to plan participants or operations. Outside the office, Tom brings that same relentless drive to endurance athletics — a veteran of over 15 marathons and 8 Ironman finishes across the globe, he knows better than most what it takes to prepare for the long course and finish strong.
