 // . //  Our People // Marianne Debains

Marianne is a Partner in the Transportation and Services Practice in Paris. Her success story can be an inspiration for aspiring consultants: she began her consulting career with Oliver Wyman in 2012 as an intern right after graduating from HEC Paris, progressing to the partner’s role within less than 10 years.

Marianne’s area of focus is strategy and performance transformation of B2B services: she helps clients accelerate top-line growth through strategic reviews and shape and realize large-scale performance transformation programs enabling sustainable value growth. Clients value Marianne for her expertise and ability to solve difficult problems, but also for her contagious enthusiasm which makes people follow her on a journey to creating a lasting impact. Many consider her a role model in terms of disruptive strategic thinking.

I have always been a great believer in people’s power to develop winning strategies and transform businesses.

Outside of work, Marianne recharges batteries by staying active (she particularly likes running), going to art exhibitions and to the cinema. As a mom of two toddlers, she values family time with her loved ones.
