Our Founder’s Message
My journey began in Kinshasa in the early 1970s, where I was born into a world rich with culture and complexity. At a very young age, I was adopted by a white Belgian family living in Kinshasa, and my adoptive father, Robert Defise, was a close friend of my biological father, Nsiona Kuzubula Ignace. This unique relationship gave me a dual cultural heritage, instilling in me an ability to bridge perspectives and embrace diversity from an early age.
