Lucille Ossai is an international award-winning communications trainer. She is also a coach, advisor, keynote speaker, and multi-award-winning blogger. She’s the author of the communications bestseller ‘Influence and Thrive: How Professionals, Entrepreneurs, Business Leaders, & Corporations Use Effective Communication To Get Results’.

Lucille is the founder of Rethinking Business Communications Limited. Her training company offers coaching, training, and advisory services on nonverbal communication, public speaking, interpersonal communication, business writing, and leadership communication and influence. She works with professionals, executives, entrepreneurs, and leaders to amplify their influence and results. For her programmes, she applies her significant experience facilitating lectures and executive seminars at the prestigious, FT-ranked Lagos Business School. Her clients include World Commerce & Contracting, the Nigeria Stock Exchange, Nestlé Nigeria, the Society of Petroleum Engineers (Lagos Chapter), and Ischus Consulting. 

Fuelled by her two-decade obsession with effective communication, Lucille developed the Global 4-Domain Communication Skills Rating Tool™ (beta). It is the first culturally intelligent global assessment that integrates the four most critical communication domains: nonverbal and interpersonal, verbal communication (public speaking and presentations), business writing, and leadership communication and influence. Its diagnostic and prescriptive model delivers objective insights, professional benchmarks, and a bias-free evaluation for leaders and organisations. The evaluation system is grounded in her proprietary frameworks:  ABF Formula, Three Rules of Business Writing, and the Flexible Communications Strategy. It is further supported by academic research and practitioner insights, providing depth, clarity, and measurable results.

Her expertise is globally recognised. In 2025, Global Gurus, the prestigious research organisation, ranked her the #7 communication professional in the world. She’s the only African to appear in the communication category. In 2021, the University of Leicester featured Lucille’s book and highlighted her work in their alumni #CitizensOfChange initiative. In May 2020, the London School of Economics & Political Science named her ‘Alum of the Month‘ for her profile and impact.  

As the writer and editor of the multi-award-winning Rethinking Business Communications Blog, Lucille provides deep insights and practical techniques on effective communication. Her recommendations will help you thrive in your career or business. Her blog is also the only African-based website to feature in Feedspot’s authoritative list of the top 40 communication blogs on the web.

Her pieces are also lauded. Lucille’s academic technical note is featured on The Case Centre (UK). Moreover, her articles have also appeared in BizCatalyst 360, Enterprising Africa, and BusinessDay Nigeria.

When this bestselling author doesn’t obsess about effective communication, she watches television to unwind. A huge fan of detective programmes, she fancies herself an expert in identifying the culprits. She also enjoys watching thrillers, (meaningful) action flicks, and dramas.

Lucille lives in Lagos, Nigeria, with her family.
