This creates a real impact as these areas are inseparable, and key to grow resilient, future-proof business”, says Niina Rantti.

Her leadership will be instrumental in developing offerings that truly respond to our clients’ most complex and meaningful challenges”, says Antti Salomaa, Managing Director, Miltton.

“Our operating environment is currently highly turbulent, and at the same time, a more systemic approach is increasingly needed. Niina’s expertise in combining sustainability with foresight and business strategy will help our clients turn global challenges into opportunities. I look forward to working with her to deepen our impact and strengthen Miltton’s role as a trusted advisor in this space,” says Terhi Koipijärvi, Senior Advisor, Miltton
