A passionate facilitator, academic director and executive coach, Isabelle Bester founded Viva Leadership International with one conviction: when organizations truly care for their people, performance follows.
Drawing on over 15 years of international experience, she partners with leaders and teams to grow through science-based assessments, high-performance learning journeys® and meaningful coaching that transforms potential into impact.
Through her programs, leaders don’t just grow their skills, they elevate the culture around them, creating organizations where people and performance thrive together.
Real People. Real Transformation.
Because every story of growth starts with someone who chose to change.
Isabelle’s magic lies in a unique blend of expertise, a deep understanding of business challenges, and remarkable emotional intelligence: she connects and empathizes effortlessly, even remotely. I was truly impressed by her impact.
Clémence Bodart – Head of Marketing, Amazon
For six months, I had the opportunity to work with Isabelle on my leadership growth. Her empathy, passion, and deep understanding made every session impactful. Isabelle quickly identified what I needed, offering clear, tailored guidance. Her approach asking the right questions and providing examples that fit my personality helped me set boundaries and apply these learnings both professionally and personally.
Cheral Olthaar – Senior Leader in Global Sourcing and Development, Hugo Boss
Having Isabelle as a facilitator for my six-month Growth Agent program at Oracle was truly rewarding. From the very first session, her energy, passion, and authenticity stood out. Isabelle creates an environment where participants feel both challenged and supported, making every learning experience engaging and impactful. Her genuine commitment to helping others unlock their full potential sets her apart.
Maryam Shoaie – Territory Sales Manager, Oracle.com
Working with Isabelle has been the only coaching experience that truly created meaningful and lasting change for me. Unlike traditional approaches focused only on the mind, Isabelle helps explore the emotions that drive behaviour and provides practical tools to recognize and transform them. This foundation builds emotional intelligence, empathy, and more impactful leadership behaviours.
Rob Samet – Transformation & Transition Leader
Working with Isabelle Bester was truly transformative. She’s more than a coach, she is a catalyst for change. Her passion and ability to inspire reflection and action are unmatched. Through the Leadership Skills Wheel, Isabelle helped us strengthen key skills from self-awareness to accountability in a way that was both empowering and deeply human. I left with practical tools and a renewed sense of purpose as a leader.
