Our Journey at ONCG LTD

With the initiative of Olivier Ntawuyirushintege, the Managing Partner & CEO, ONCG LTD was established in 2017 with its former name ON & Associates Ltd which later changed to ON Consulting Group (ONCG) Ltd. Since its founding in 2017, ONCG LTD worked with a pool of qualified experts and professionals in the industry with the aim of proving the service of the high quality level and based on the latest professional knowledge, this had boosted up its performance in the industry and demonstrated the speedy progress it is making to aid in bringing about positive change. We did this by acting publicly and leading by example for others to follow, we also looked for feedback from all of our stakeholders so that they became a part of our journey. The road map is currently illustrating this.
There is a lot more to do on our updates, as part of our dedication and vision, concentrating on the important issues methodically and with purpose, identifying the risks and possibilities, and helping those who might not have been on the path that produced the actionable insight to see them. We shall do more of the things we have to accomplish.
When we work together to create this good change, our customers, ourselves, and the majority of society all win. This will build confidence and empower change.
Meeting our obligation takes many different forms, including the values we uphold and the caliber of the work we produce in both our professional and personal lives. We sincerely believe that the business community has a chance and a duty to contribute to creating a more sustainable future now more than ever. Because of this, ONCG is hoping to be recognised as the best among the best performers in the field to compile a list of all of our commitments to governance, social responsibility, and the environment.
