Michael J. Gresalfi, Ph.D.

Chief Product Officer

Michael has enjoyed a 35-year career, primarily as an executive-level advisor to both corporate leaders and government officials. A service-connected disabled veteran and former counterintelligence officer with the U.S. Army, Michael has functioned as an interlocutor on matters of national security between federal agencies, as well as being a trusted facilitator to previous organizations’ executive teams. 

Gifted with a naturally gregarious disposition and strong interpersonal skills, he is affectionately considered a “consigliere” by several Assistant Secretary level government officials he supported as a senior advisor in the post-9-11 era, where he primarily focused on both counter-terrorism and mitigating other threats to our national security posture.

Michael is skilled at ensuring that an organization’s leadership team is fully aligned with corporate strategic goals and objectives and that senior management lines of authority work in concert, supporting both the right products and shared corporate outcomes.

Calling upon his multi-agency and corporate experiences, which included leadership careers as an officer with the U.S. Army, as well as management and advisory positions with Science Applications International Corporation (SAIC), Booz Allen Hamilton, and Oak Ridge National Laboratory, Michael ensured that executives running different functional areas work together seamlessly toward achieving shared strategic goals. 

In addition to completing the Senior Executives in National and International Security certificate program at Harvard’s Kennedy School of Government, Michael received his Ph.D. in policy-making from the George Washington University and an M.A. in Government from the College of William and Mary.
