Company’s No. 2 employee takes on expanded leadership role as Directorie enters its next phase of growth
CHESTERFIELD , MO, UNITED STATES, August 31, 2026 /EINPresswire.com/ — Directorie, a fast-growing commercialization partner for the pharmaceutical and biotech industries, today announced the promotion of Thomas McGuire to president, effective immediately.
As the company’s No. 2 employee, McGuire has shaped Directorie from its earliest days, building teams, strengthening client partnerships and helping establish the culture and standard of excellence that have fueled its growth. Throughout his tenure, McGuire has served as a leader across Client Excellence, overseeing Directorie’s client portfolio from business development through ongoing partnership across a wide range of therapeutic areas, care settings, treatment modalities and the full product lifecycle. Beyond individual client engagements, he has played an instrumental role in advancing Directorie’s client relationships and helping organizations navigate complex challenges to achieve meaningful results. “Thomas has an extraordinary ability to activate the potential in people, in teams, in our clients and in this company,” said Erika Sinner, founder and CEO of Directorie. “He helps people see the very best in themselves while holding an incredibly high bar for what we can accomplish together. He has been part of building Directorie from the beginning, and I could not be more excited for what his leadership will mean for our people, our clients and our future.”
Building Directorie’s Next Chapter
McGuire’s promotion comes as Directorie evolves its leadership structure to support continued growth. In his new role, he will work closely with Sinner and Directorie’s leadership team as the company builds on significant momentum, including recognition on the Inc. 5000 list of America’s fastest-growing private companies in 2024, 2025 and 2026. “Having built Directorie from its earliest days, I’ve lived what it means to make this company successful, and I’m even more excited about what comes next,” said McGuire. “We have amazing people, trusted clients and a clear runway to success. My responsibility as president is to turn those strengths into even greater opportunity: for our teams to do the best work of their careers, for our clients to achieve things they couldn’t achieve without us, and for Directorie to continue raising the standard for what a valued partner can be. We’ve accomplished a lot in eight years, and I know we’re just getting started.”
