    What our partners say

    M&O Partners has managed our operations in Brazil since February 2015, leading a thorough downsizing and restructuring process. They were able to provide us with an experienced and efficient team in Rio, filling key management roles with internationally qualified, trustworthy and multidisciplinary in-house staff. The communication between Rio and Norway has been excellent. The M&O Team has proven to be a very cost efficient management solution for us.
