Who Is Gregory MacKenney Sr.?
Gregory MacKenney Sr. is a global business executive, leadership coach, and the Founder & CEO of GM Titan and Associates LLC. With more than 25 years of experience spanning engineering, operations, and executive leadership, he has led global teams and managed divisions exceeding $500 million in revenue. A graduate of Morgan State University and Cornell University, Greg blends technical expertise with people-centered leadership. Through his ACCE framework—Adaptability, Clarity, Courage, and Empathy—he coaches high-impact leaders to scale both performance and purpose. His mission is to help organizations grow by investing in human potential, empowering leaders to create lasting impact within their teams, communities, and industries worldwide.
The Power of Presence
Long before Gregory MacKenney Sr. managed nine-figure P&Ls or coached executives across five continents, he was a young man in Baltimore observing a masterclass in leadership that no Ivy League school could replicate. The curriculum wasn’t found in textbooks, but in the way his grandfathers moved through the world—at home, in the church pews, and within their professions. They demonstrated a rare, multi-dimensional presence: the ability to lead with equal parts strength and grace regardless of the setting.
For Greg, leadership was never a title to be claimed; it was a way of being to be cultivated. This foundational realization—that true leadership is a 360-degree commitment—has become the hallmark of his twenty-five-year journey. Today, as the Founder and CEO of GM Titan and Associates LLC, Greg doesn’t just consult on business strategy; he helps leaders reclaim their “why” and transform their organizations by first transforming themselves.
The Baltimore Blueprint
Greg’s journey began in the vibrant community of Baltimore, Maryland, where the values of hard work and community service were non-negotiable. His professional path was ignited at the age of 14 through a city summer jobs program, where he earned less than $4 an hour as a camp counselor. This early exposure to the workforce proved “invaluable,” teaching him the mechanics of professional development long before he stepped onto a college campus.
Driven by a natural aptitude for problem-solving, Greg pursued a rigorous academic path, earning a B.S. in Electrical Engineering from Morgan State University followed by a Master of Electrical Engineering from Cornell University. These institutions provided the technical scaffolding for his career, but it was his upbringing that provided the soul. He learned early on that the most complex systems aren’t built of wires and circuits, but of people and their shared aspirations.
The Global Executive
In 2000, Greg joined Agilent Technologies as a Manufacturing Development Engineer, earning a starting salary of $60,000. Over the next quarter-century, his career trajectory was a testament to his “ACCE” leadership philosophy: Adaptability, Clarity, Courage, and Empathy. He didn’t just climb the corporate ladder; he rebuilt it to be more inclusive and global in scope.
Rising through the ranks to become Vice President and General Manager, Greg eventually shouldered the responsibility for a $500M+ division. His tenure was defined by a unique ability to bridge the gap between high-level R&D and bottom-line profitability. He led global teams across manufacturing, quality, and services, consistently delivering high-single-digit revenue growth and profitability exceeding 40%. Yet, for Greg, the most significant metric wasn’t the revenue—it was the $9M in university donations he championed and the double-digit growth he fostered in emerging markets like China and India.
The Titan of Transformation
In September 2025, Greg transitioned from the corporate executive arena to the founder’s seat, launching GM Titan and Associates LLC. The firm is the culmination of his life’s work, blending his engineering precision, twenty-plus years of corporate leadership, and the Marshall Goldsmith Stakeholder Centered Coaching methodology. Greg’s impact is now measured by the “Return on Coaching” he helps his clients calculate—not just in terms of revenue, but in time reclaimed for higher-value work, the psychological safety of their teams, and improved stakeholder perception of their leadership.
His peers recognize him as a “guiding presence” who remains approachable even in high-pressure environments. Whether he is volunteering at the Reginald F. Lewis Museum or mentoring a young professional, his guiding principle remains the same: “The best investment you can make is into someone else”.
A Vision for the Global Century
As we move further into an era defined by AI and rapid disruption, Greg’s focus has shifted toward the next frontier of leadership. He is a vocal advocate for Gen Z, urging them to “find and pursue your why,” maintain a growth mindset, and dedicate themselves to helping others. His own “why” is clearer than ever: to catalyze transformation on a grand scale, empowering leaders and institutions to ignite positive change that radiates meaningful impact throughout communities and the world, inspiring global progress and a legacy of excellence. He plans to expand his coaching portfolio into Africa, completing coverage of the populated world, further solidifying his global leadership legacy.
Greg MacKenney Sr. is not just building a business; he is architecting a movement of leaders who understand that empathy and courage are the most valuable currencies in the modern economy. His story serves as a reminder that while careers are built on milestones, legacies are built on the lives we elevate along the way.
