While working in Africa, I observed that all of the African Chiefs had a personal advisor to aid them in successfully completing their work. I had come to learn that there was a name for this person: ‘NDUNA’ – which translates to “Executive Advisor to the Chief.”

Remembering this concept when starting my own business, the name NDUNA fit so effortlessly as this is exactly what I consider myself to be to my clients – an Executive Advisor to the Chief. My job is to help you. Help you change your leadership behavior and leverage your leadership potential, and partner with you to help you to become a real performer.

As your Executive Coach, I believe that personal development is a cornerstone of leadership development and that if you want to grow your leadership success, you need to grow your personality traits.

We start by making you stop bulshi*ting yourself. And other people.

Together, we analyze your identity and your leadership behavior. We measure your dark sides of leadership. We explore your value system. We combine the data and make a leadership portrait that tells the truth – like a mirror.

We look for your dreams – your aspirations. We revitalize the energy from your previous leadership successes, and we build a vision and mission.

A ship. A course. A crew. And you set the sails. Be the Captain in your own life.

Connect with me to serve as your Executive Advisor – your NDUNA.

Technical skills are not enough anymore to secure a successful career. If you can’t collaborate, communicate, relate, and coordinate well enough with your colleagues in the team and with other cross-functional teams inside and outside the organization, you’ll have a hard time getting things done to reach the desired productivity level.

The ability to work well in a team takes a lot of soft skills, also called, Essential Skills, Social Skills, or Interpersonal Skills.
NDUNA specializes in helping you become aware of the soft skills gap you might have. And we help you close the gaps and optimize your team performance behavior.
