From the submarine service to the boardroom. Three decades of building, operating, and transforming businesses across continents, cultures, and markets.
Terry J. Ingram is the CEO of Ingram Advisory Group and the architect of its immersive, operator-led advisory model. His career began in the U.S. Navy Submarine Service, where he learned the discipline of operating complex systems under pressure — lessons that would shape every business decision to follow.
After his service, Terry moved into the operating world, serving as CEO and President of Allagash International, where he built and scaled multiple companies globally. He has steered organizations across marine, industrial, and commercial manufacturing sectors, successfully expanding operations in the Americas, Asia-Pacific, Europe, and the UAE.
A strategic visionary and hands-on leader, Terry has honed a unique blend of skills that drive corporate growth through start-ups, acquisitions, turnarounds, and international partnerships. His proven track record in operational excellence is complemented by his active role in corporate governance, where he brings a collaborative approach to shaping global business landscapes.
Terry's advisory work focuses on the intersection of leadership, operations, and capital. Whether the engagement is a growth initiative, a restructuring, a succession plan, or a transaction, he brings the perspective of someone who has sat in the operator's chair — not just the advisor's seat. He has led engagements across global and domestic manufacturing, technology, distribution, pharmaceutical development, food processing, and professional services sectors.
IAG partners bring deep, cross-functional expertise from decades of operating experience across domestic and international markets. Each engagement is led by a senior operator who has built, scaled, exited, or restructured businesses in the real world.

Where traditional consulting stops at recommendations, IAG embeds itself within your organization. We don't simply advise — we implement, adapt, and drive change in real time. By the time our engagement concludes, you aren't just equipped with a roadmap — you're already on your path to achieving your goals.
From Fortune 500 companies to ambitious start-ups, pharmaceutical development to food processing, technology to distribution — our tailored strategies ensure impactful results. We specialize in manufacturing processes, distribution networks, and operational systems, but our reach spans every sector where structure and execution determine outcomes.
We fix the business behind the business — financial truth, operating discipline, governance, and transferable value — before growth, transition, financing, or exit exposes what is missing. Our clients gain more than a plan — they gain a head start on sustainable success.
