Sherese Duncan, CEO & President

Sherese Duncan’s journey as CEO of Effició, Inc. is a testament to her innate ability to advise, analyze, and solve problems with exceptional clarity and effectiveness. Hailing from the “show me state” of Missouri, Sherese has always defied the odds, elevating platforms, and paving unexpected paths. Armed with a natural inclination for logical decision-making, Sherese embarked on her entrepreneurial journey in the early 2000s after earning her MBA degree, founding Effició with a vision to empower entrepreneurs and position them for self-actualization.

For over two decades, Sherese has championed entrepreneurship, providing invaluable education and training to entrepreneurs, professionals, business owners, and organizations worldwide. As she pursues her Ph.D. at Luleå University of Technology in Sweden, Sherese is extending Effició’s intellectual capital to pioneering research in entrepreneurship, marketing, economic intelligence, and power relationships.

Her business approach, rooted in practicality and efficacy, has consistently delivered success. Sherese Duncan exceeds her definition of success by being a catalyst for entrepreneurial excellence, guiding individuals and organizations toward deep, CORE, rooted achievement.

Duncan isn’t just a powerhouse in the boardroom; she’s an adventurer at heart. You’ll often find her on the tennis court, scaling rock walls, or exploring nature’s wonders on adventurous expeditions. When she’s not conquering athletic challenges, she’s exploring the vibrant culinary scene in Charlotte, savoring the latest culinary creations at new restaurants, or simply unwinding with her husband on one of the many beautiful beaches along the North Carolina coast.

But Sherese’s interests extend far beyond athletics and cuisine. An avid advocate for the arts, she dedicates her leisure hours to nurturing young minds through organizations focused on promoting fine arts, musical education, literacy, and expanding access to enriching experiences. When she’s not engrossed in business matters, Sherese’s passion for exploration takes her to distant corners of the globe, where she immerses herself in learning, embracing new cultures, and, of course, sampling local cuisine. With a zest for life that transcends the boardroom, Sherese Duncan embodies the perfect blend of adventure, creativity, and entrepreneurial spirit.
