Diana Emily Rheault — Co-Founder

As the Founder of The Trifocal Advisor, my firm provides a premium, high-trust advisory service that helps life sciences, medical device, and portfolio company leaders execute high-stakes transformations, bridge the gap between strategy and execution, lead through complex change, and build emotionally intelligent teams that unlock value as a strategic advantage. We go beyond traditional consulting—bringing deep operational expertise and a people-first lens—because no strategy succeeds without people executing it. We embed emotional intelligence throughout every engagement, not as a nice-to-have, but as a business-critical lever because peak business performance is a direct outcome of peak human performance. Before launching my advisory practice, I spent more than two decades inside the system, first at Deloitte, advising global healthcare clients on large-scale transformations and mission-critical initiatives. Later, at Pfizer, I served as an operator within Commercial Development, leading U.S. and global launches, customer insight efforts, and the development of market-shaping strategies. That dual lens—𝗔𝗱𝘃𝗶𝘀𝗼𝗿 𝗮𝗻𝗱 𝗢𝗽𝗲𝗿𝗮𝘁𝗼𝗿—continues to shape everything we do.
