Gregory’s professional journey began in the advertising and communications industry, where he developed a deep appreciation for the relationship between consumer behavior, brand perception, and commercial success. At J. Walter Thompson, one of the world’s most recognized advertising agencies, he advanced through increasingly senior leadership positions, ultimately serving as Vice President and Management Supervisor. During his tenure, he managed major client relationships and contributed to strategic marketing initiatives for prominent brands, including Sunsweet, Jenny Craig, E. & J. Gallo, Supercuts, and American Hawaiian Cruises. These formative experiences sharpened his ability to translate complex market insights into compelling business strategies while establishing the foundation for his expertise in brand development, organizational leadership, and customer engagement.
Building upon this foundation, Gregory joined Foote, Cone & Belding Worldwide, now known as FCB Global, where he rose to Executive Vice President and Worldwide Account Director. In this capacity, he assumed substantial profit-and-loss responsibility, directed multidisciplinary teams, and oversaw major global accounts representing hundreds of millions of dollars in client spending. His leadership contributed to transformational marketing initiatives for AT&T Wireless, Avaya Communications, and Taco Bell. Among his most notable accomplishments was spearheading the introduction of AT&T Digital One Rate, a groundbreaking national wireless offering that helped accelerate subscriber growth and reshape consumer expectations for mobile communications. He also played an instrumental role in reversing a multiyear decline in customer traffic at Taco Bell through strategic brand repositioning and the influential “Think Outside the Bun” campaign. These achievements demonstrated his ability to connect creative innovation with measurable financial and operational outcomes.
Gregory subsequently brought his strategic capabilities to Intel Corporation, serving as Vice President and Director of Global Brand Strategy and Advertising. Responsible for guiding major global branding initiatives and managing significant marketing investments, he helped position Intel at the forefront of technological innovation during a pivotal period in the evolution of personal computing. His leadership was central to the worldwide launch of Intel Centrino Mobile Technology, a transformative platform that helped usher in the era of mobile computing. The launch achieved participation from all of Intel’s leading global original equipment manufacturing partners and supported first-year sales of approximately seven million units. Beyond this landmark achievement, Gregory strengthened partnerships with telecommunications providers, aligned brand strategies with product development roadmaps, improved global advertising processes, and negotiated agency agreements that generated multimillion-dollar cost savings. His work demonstrated a sophisticated understanding of how technology, customer insights, operational efficiency, and strategic positioning intersect to create competitive advantage.
Following his tenure at Intel, Gregory became a Partner at Prophet Brand Strategy, a global strategic consulting firm, where he advised major corporations on business transformation, market positioning, and organizational growth. Working with companies including Cargill, Hewlett-Packard, and Electronic Arts, he helped leadership teams identify emerging opportunities, strengthen market relevance, and align organizational capabilities with long-term strategic objectives. His contributions included developing a global master brand strategy and organizational framework for Cargill that laid the groundwork for increased brand equity, as well as helping Hewlett-Packard strengthen its competitive positioning in premium printing products. These engagements reinforced his expertise in navigating complex corporate environments, building executive consensus, and translating strategic recommendations into practical initiatives.
Driven by an entrepreneurial spirit and a commitment to helping organizations realize their full potential, Gregory founded Sieckgrowth Consulting in 2005.

These experiences strengthened his appreciation for the intersection of healthcare innovation, institutional leadership, and community well-being, areas in which he remains particularly interested in making a lasting contribution.
