What Our Clients Are Saying



The 5 day intensive session was made easy and interesting!

My colleagues and I were well trained and no stone was left unturned. Everyone of us understood all that we needed to do to ensure that our organisation got certified. Even after our training, the support from Sunkanmi and Seye was fantastic as they gave us advice and even helped us to review our Quality Policy. For me, I felt it wasn't just a business contract for them but an investment which culminated in 3 companies in the Stanbic IBTC Group getting ISO 9001:2015 QMS certified within 6 months!

Their service is not business as usual, they go the extra mile to deliver on client's requests!

I have been opportuned to experience first class customer service and professionalism with OAK Interlink in my capacity as a Technical Learning and Development Expert in MTN Nigeria. I must confess, their service is not business as usual, they go the extra mile to deliver on client's requests which is mostly new considering the evolving technology and diversified nature of our business. In terms of cost saving, they have partnered with us to reduce cost, most especially our travel cost by being able to import special skills that we used to purchase in European countries. MTN Nigeria has been their consistent customer over the past years and we have never had a reason to push back. Thank you.
