Lucille Ossai

Lucille Ossai is an internationally acclaimed communications innovator and keynote speaker who helps leaders communicate with clarity, confidence, and cultural intelligence in high- stakes global environments. Ranked #7 worldwide by Global Gurus in 2025 — the only African-born expert in the global Top 10 — she brings a Global South perspective that is reshaping how multinational leaders influence across cultures, hierarchies, and power dynamics.

She is the Amazon bestselling author of "Influence and Thrive" and the creator of the Global 4- Domain Communication Skills Rating Tool™ — the first comprehensive framework integrating cultural intelligence with four-domain communication assessment across nonverbal and interpersonal skills, public speaking, business writing, and leadership communication and influence. Her work challenges traditional Western-biased models and introduces fairer, bias-reduced approaches to measuring executive communication across regions.

For over a decade, Ossai has designed and delivered executive communication programs at the Financial Times-ranked Lagos Business School, where her sessions have earned ratings of up to 4.9/5. She has worked with over 1,000 senior leaders and professionals, partnering with organizations such as Nestlé Nigeria, the Nigeria Stock Exchange, World Commerce & Contracting, and the Society of Petroleum Engineers (Lagos Chapter).

Her work has earned recognition from senior global leaders. In 2023, Sally Guyer, the Global CEO of World Commerce & Contracting, described Ossai's keynote for the organization as "impactful and inspiring," noting that the audience greatly valued her practical strategies for improving business communication.

Her proprietary frameworks — the ABF Formula™ for persuasive speaking, the Three Rules of Business Writing™ for sharp, compelling, and grammatically correct writing, and the Flexible Communications Strategy™ for high-stakes messaging — have been validated through continuous delivery in MBA and Executive MBA programs since 2015. They give executives immediately actionable tools for complex communication challenges.

She was named Top Communications Trainer of the Year by the International Association of Top Professionals (USA) and has been featured by The London School of Economics & Political Science and the University of Leicester. Her thought leadership appears in The Case Centre (UK), Thinkers360, BizCatalyst 360, and BusinessDay. Her Rethinking Business Communications blog is the only African-based platform consistently ranked in Feedspot's global Top 40 communication blogs.

Global organizations engage Ossai to solve a critical challenge: how to assess and develop communication talent fairly across cultures whilst driving measurable business outcomes. Clients report transformational impact — from marked improvements in communication quality and team effectiveness to enhanced leadership presence and executive influence.

She is trusted by executives, leadership teams, and high-performance professionals to build influence, strengthen leadership presence, and drive results through communication.
